The Cell Cycle and its Regulation

Shortcut Guy Regulation

Your cells have to divide when you’re growing, to heal wounds, and to replace dead cells. But how do cells know when to divide and when not to divide? We can’t have cells just growing willy-nilly! That’s what cancer is, and that’s bad. Luckily, cells obey something called the cell cycle, which is regulated by a variety of signaling molecules, which tell the cell when to divide and when to chill out. Let’s look at the phases […]

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

Shortcut Guy 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: Operons, Epigenetics, and Transcription Factors

Shortcut Guy 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!
