Lecture Molecular biology (Fifth Edition): Chapter 6 - Robert F. Weaver

Chapter 6 - The mechanism of transcription in bacteria. In this chapter we will focus on the basic mechanism of transcription. We will begin with RNA polymerase, the enzyme that catalyzes transcription. We will also look at the interaction between RNA polymerase and DNA.

Lecture Molecular biology (Fifth Edition): Chapter 10 - Robert F. Weaver

In chapter 6 we learned that bacteria have only one RNA polymerase, which makes all three of the familiar RNA types: mRNA, rRNA, and tRNA. In this chapter we will see that three distinct RNA polymerases occur in the nuclei of eukaryotic cells. Each of these is responsible for transcribing a separate set of genes, and each recognizes a different kind of promoter.

Lecture Molecular biology (Fifth Edition): Chapter 11 - Robert F. Weaver

Chapter 11 - general transcription factors in eukaryotes. Eukaryotic RNA polymerases, unlike their bacterial counterparts, are incapable of binding by themselves to their respective promoters. Instead, they rely on proteins called transcription factors to show them the way. Such factors are grouped into two classes: general transcription factors and gene-specifi c transcription factors (activators). In this chapter we will survey the general...
