Examining Gene Expression & Regulation | Live Review Session 5 | AP Biology

Regulation

In this AP Daily: Live Review session for AP Biology, we will review gene expression and regulation, including nucleic acids & their role in gene expression. We look at replication, transcription, RNA processing & translation. We’ll highlight four topics in Unit 6: Gene Expression and Regulation. We start with Topic 6.2: Replication to examine the mechanisms by which genetic information is copied for transmission between generations will be reviewed. We will discuss how to explain relationships between […]

Regulation of gene Expression | Lac Operon | Biology

Regulation

The regulation of gene expression Gene regulation is the process of controlling which genes in a cell’s DNA are expressed (used to make a functional product such as a protein). The lac operon • The lac operon of E. coli contains genes involved in lactose metabolism. It’s expressed only when lactose is present and glucose is absent. • Two regulators turn the operon “on” and “off” in response to lactose and glucose levels: the lac repressor and […]

Regulation of Gene Expression: Operons, Epigenetics, and Transcription Factors

Regulation

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! Watch the whole Biology/Genetics playlist: General Chemistry Tutorials: Organic Chemistry Tutorials: Biochemistry Tutorials: Anatomy & Physiology Tutorials: […]

Gene Regulation

Regulation

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?
