We learned about gene expression in biochemistry, which is comprised of transcription and translation, and referred to as the "central dogma" of molecular biology. But how is this process regulated? How does a cell know which genes to express and when? Well it's pretty complicated, but let's just get our feet wet by looking at operons, epigenetics, and transcription factors!

Gene regulation in eukaryotes
 
10:39
Gene regulation in eukaryotes - This lecture explains about the eukaryotic gene regulation. Regulation of gene expression entails a vast variety of mechanisms which can be utilized by cells to expand or shrink the creation of particular gene products (protein or RNA), and is informally termed gene legislation. Subtle packages of gene expression are greatly found in biology, for illustration to set off developmental pathways, reply to environmental stimuli, or adapt to new food sources. Virtually any step of gene expression can also be modulated, from transcriptional initiation, to RNA processing, and to the post-translational change of a protein. Gene regulation is main for viruses, prokaryotes and eukaryotes because it raises the flexibility and adaptability of an organism via permitting the cellphone to specific protein when needed. Although as early as 1951 Barbara McClintock confirmed interaction between two genetic loci, Activator (Ac) and Dissociator (Ds), in the color formation of maize seeds, the first discovery of a gene law approach is widely regarded to be the identification in 1961 of the lac operon, learned through Jacques Monod, in which some enzymes involved in lactose metabolism are expressed by using the genome of E. Coli handiest within the presence of lactose and absence of glucose. Furthermore, in multicellular organisms, gene regulation drives the processes of cellular differentiation and morphogenesis, main to the creation of unique cellphone forms that possess different gene expression profiles, and therefore produce one of a kind proteins/have special ultrastructures that suit them to their capabilities (although they all possess the genotype, which follows the equal genome sequence). The initiating event main to a transformation in gene expression include activation or deactivation of receptors. Additionally, there's proof that alterations in a mobile's option of catabolism results in altered gene expressions.

A2 Biology - Transcriptional control of gene expression (OCR A Chapter 19.2)
 
05:45
Here we'll be looking at the first level of gene expression regulation in eukaryotes, which is before transcription. The principle of this stage is to switch genes on or off, and this is decided by whether or not the RNA polymerase is allowed to bind to the gene for transcription to happen. This is dependent on the state of the chromatin which is altered by histone modification - if the histones are less positively charged (ie. more negative), the DNA will become less tightly wound around it, allowing the gene to become accessible to the RNA polymerase for transcription.

Gene regulation in prokaryotes
 
07:05
This lecture explains about the Gene regulation in prokaryotes. Regulation of gene expression entails a broad range of mechanisms that are used by cells to develop or diminish the production of specific gene products (protein or RNA), and is informally termed gene legislation. Subtle applications of gene expression are greatly located in biology, for example to trigger developmental pathways, respond to environmental stimuli, or adapt to new food sources. Practically any step of gene expression may also be modulated, from transcriptional initiation, to RNA processing, and to the put up-translational amendment of a protein. Gene law is main for viruses, prokaryotes and eukaryotes as it raises the flexibility and suppleness of an organism via allowing the mobile to express protein when wanted. Despite the fact that as early as 1951 Barbara McClintock confirmed interplay between two genetic loci, Activator (Ac) and Dissociator (Ds), within the color formation of maize seeds, the primary discovery of a gene legislation procedure is largely regarded to be the identification in 1961 of the lac operon, learned by means of Jacques Monod, where some enzymes concerned in lactose metabolism are expressed with the aid of the genome of E. Coli most effective in the presence of lactose and absence of glucose. Furthermore, in multicellular organisms, gene legislation drives the approaches of mobile differentiation and morphogenesis, leading to the creation of specific mobilephone types that possess distinct gene expression profiles, and as a consequence produce distinctive proteins/have different ultrastructures that swimsuit them to their features (though all of them possess the genotype, which follows the equal genome sequence). The initiating event leading to a change in gene expression comprise activation or deactivation of receptors. Also, there may be evidence that alterations in a cell's choice of catabolism results in altered gene expressions.

Molecular Biology of Gene
 
07:28
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product. These products are often proteins, but in non-protein coding genes such as ribosomal RNA (rRNA) genes or transfer RNA (tRNA) genes, the product is a functional RNA. The process of gene expression is used by all known life - eukaryotes (including multicellular organisms), prokaryotes (bacteria and archaea) and viruses - to generate the macromolecular machinery for life.

Difference between Prokaryotic and Eukaryotic Gene Expression

Prokaryotic gene expression vs eukaryotic gene expression - This lecture explains about the difference between Prokaryotic and Eukaryotic gene expression. Prokaryotic gene expression is simple and it occurs in the cytoplasm of the cell including DNA Replication, transcription and translation while gene expression in eukaryotes are complex and it contains several stages. The process of DNA Replication takes place inside the nucleus but the protein synthesis takes place in Cytosol. Eukaryotic RNA is modified by polyadenylation and splicing prior to the protein synthesis and it is regulated in several different levels. While the Prokaryotic gene expression is regulated by the Operon concept while the expression of genes regulated by a single promoter and operator gene.

How Genes are Regulated: Transcription Factors
 
02:56
Like us on Facebook: https://www.facebook.com/pages/Stroma-Studios/290868104261105?sk=wall Each cell in our body inherits the same master copy of DNA, but different cell types use it differently. Transcription Factors help influence which genes are used in which cell. Understanding how these dynamic proteins physically interact with DNA allows us to better understand and model their binding to DNA and their regulation of gene expression.

Regulated Transcription
 
03:38
NDSU Virtual Cell Animations Project animation "Regulated Transcription". For more information please see http://vcell.ndsu.edu/animations. Gene expression is controlled in many different ways. When proteins from outside a cell signal for a specific gene to be transcribed, it is known as regulated transcription. This animation illustrates how a protein like insulin can trigger a regulated transcription event, in addition to setting off the signal pathway illustrated in our Insulin Signaling video.

A2 Biology - Homeobox genes (OCR A Chapter 19.3)
 
05:08
There isn't loads you need to know about homeobox genes, but simply what it is and what would be affected if it is mutated. Homeobox/Hox genes are regulatory genes that control body development, basically telling where the organs should go. If a mutation occurs, a deformed individual will be made. Here we will discuss that in a bit more detail and see how it links to mitosis and apoptosis.

Lac Operon - gene regulation in prokaryotes
 
13:24
This lecture explains the lac operon and the regulation of gene expression in prokaryotes by lac operon. The lac operon consists of three structural genes, and a promoter, a terminator, regulator, and an operator. The three structural genes are: lacZ, lacY, and lacA. lacZ encodes β-galactosidase (LacZ), an intracellular enzyme that cleaves the disaccharide lactose into glucose and galactose. This video lecture will teach you the mechanism of lac operon. It will also explain the positive and negative regulation of Lac operon and how it is controlled in response to the presence of Glucose. This video will also help you to realize the difference between a catabolic and an anabolic operon.

Histone acetylation and methylation
 
11:28
This epigenetics lecture explains about the Histone acetylation and methylation. Histone acetylation and deacetylation are the approaches in which the lysine residues within the N-terminal tail protruding from the histone core of the nucleosome are acetylated and deacetylated as part of gene law. Histone acetylation and deacetylation are most important components of gene regulation. These reactions are normally catalysed through enzymes with "histone acetyltransferase" (HAT) or "histone deacetylase" (HDAC) endeavor. Acetylation is the approach the place an acetyl sensible crew is transferred from one molecule (on this case, Acetyl-Coenzyme A) to an extra. Deacetylation is readily the reverse response the place an acetyl staff is removed from a molecule. Acetylated histones, octameric proteins that organize chromatin into nucleosomes and finally better order constructions, symbolize a sort of epigenetic marker inside chromatin. Acetylation removes the positive charge on the histones, thereby reducing the interaction of the N termini of histones with the negatively charged phosphate companies of DNA. As a consequence, the condensed chromatin is modified into a more comfortable constitution that's related to higher levels of gene transcription. This leisure can also be reversed by way of HDAC pastime. Comfortable, transcriptionally active DNA is known as euchromatin. More condensed (tightly packed) DNA is referred to as heterochromatin. Condensation will also be brought on via techniques together with deacetylation and methylation; the action of methylation is oblique and has no outcomes upon charge.

Labster Virtual Lab: Gene Regulation Simulation
 
01:44
Get access here: https://www.labster.com/simulations/gene-regulation/ ABOUT THE VIRTUAL LAB SIMULATION The Gene Regulation lab is based on the Nobel Prize in Physiology 2012 case study about the development of induced pluripotent stem cells where they successfully altered the gene expression of 4 transcription factors causing the mature fibroblast cells to acquire pluripotent characteristics. SUMMARIZED LEARNING OUTCOMES - Understand how gene expression can be regulated - Understand that gene regulation takes place in mRNA, protein and epigenetics level - How to measure mRNA level using RT-PCR, protein expression using Western blot and methylation using bisulfite sequencing - Learn about stem cells and their potential use DETAILED LAB DESCRIPTION Transforming Fibroblasts to induced Pluripotency Stem (iPS) Cells The premise of the lab is to save a blind child by preparing iPS cells that will then be differentiated to retinal-pigmented epithelial cells for transplantation. First students need to determine which transcription factors are important in maintaining stem-like features. By analyzing differential gene expression between fibroblasts and stem cells, students identify the candidate genes. After identifying these genes, students use a retroviral infection technique to transform mature fibroblasts into iPS cells. Gene Expression Analysis After the transformation, students need to confirm that their selected genes are up-regulated in fibroblasts. Students need to check their mRNA transcripts by using RT-PCR and also protein levels using Western blot. The protein level does not always corroborate with the mRNA level, students learn this concept in this lab. The gene expression level can also be regulated by epigenetics, for example promoter methylation. Students investigate the level of methylation using bisulfite sequencing. After completing the Gene Regulation lab, students will understand standard techniques commonly used to analyze gene expression—RT-PCR and Western blot. Students will also learn about the epigenetic mechanism of gene regulation. More over students explore the exciting science of iPS and its potential use.

PhET Simulation Gene Machine: The Lac Operon http://phet.colorado.edu/en/simulation/gene-machine-lac-operon In this video Paul Andersen describes the elements of an operon. The promoter allows the RNA polymerase to transcribe the required genes. The operator and repressor regulate the expression of the genes by blocking the RNA polymerase. The genes for a specific task are all located in sequence so that they can all be transcribed at once. He starts be describing how the lac operon can be initiated to break down lactose. He then explains how the trp operon can be activated to create tryptophan. He ends with a simulation of the lac operon.
