Gene Regulation: Transcription Mechanisms and Chromatin Accessibility

This lecture covers the regulation of gene expression, focusing on the mechanisms of transcription and chromatin accessibility. The instructor explains how cells control the synthesis of functional products through transcription factors, promoters, and gene regulatory networks. Various mechanisms such as chromatin remodeling, DNA looping, and epigenetic modifications are discussed in the context of pre-transcription, transcription, and post-transcription stages.
