Regulation of Gene Expression: Operons, Epigenetics, and Transcription Factors
 
13:07
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!

031 - Gene Regulation Paul Andersen explains how genes are regulated in both prokaryotes and eukaryotes. He begins with a description of the lac and trp operon and how they are used by bacteria in both positive and negative response. He also explains the importance of transcription factors in eukaryotic gene expression. Do you speak another language?

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.

Gene regulation in eukaryotes

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.

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.

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.

Difference between Prokaryotic and Eukaryotic Gene Expression
 
09:35
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.

The Lac operon | Regulation of gene expression
 
05:04
The lac operon (lactose operon) is an operon required for the transport and metabolism of lactose in Escherichia coli and many other enteric bacteria. The lac operon allows for the effective digestion of lactose when glucose is not available through the activity of beta-galactosidase. Gene regulation (regulation of gene expression) of the lac operon was the first genetic regulatory mechanism to be understood clearly, so it has become a foremost example of prokaryotic gene regulation. This lactose metabolism system was used by François Jacob and Jacques Monod to determine how a biological cell knows which enzyme to synthesize. Their work on the lac operon won them the Nobel Prize in Physiology in 1965.

Prokaryotic regulation of gene expression
 
18:44
How prokaryotes regulate how actively their genes are expressed (on or off, up or down). I discuss both negative gene regulation (involving repressors) and positive gene regulation (involving activators), discussing the classic trp and lac operon systems where this was first studied.

Eukaryotic regulation of gene expression
 
09:27
Discussing additional mechanisms that eukaryotes have to control how often genes are expressed, and how often mRNAs are translated. This includes discussing additional DNA regulatory regions (enhancers, silencers), histone packing / unpacking, and RNA interference

Operon
 
10:01
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.
