Lecture, chapter 6 - Transcription in eukaryotes
Lecture, chapter 7 - Protein structure and function

Today we finished chapter 6, on transcription, specifically in eukaryotes.

We discussed the mechanism in which general and specific transcription factors aid RNA polymerase II in initiating transcription of protein-coding genes in eukaryotes. We also discussed the role of enhancer regions as sequences recognized by specific transcription factors and the role of DNA looping to allow the interaction of transcription factors that bind to the DNA far away from the gene (or transcription unit).

We also started chapter 7 on protein structure and function. We covered the characteristics of amino acids and then we started discussing the levels of structure in polymers, specifically polypeptides.
