Document Summary
Lecture 1 structure of the genome and chemical nature of dna (february 26) Chapter 10: chemical nature of dna structure of the genome. The genome before 2005: most of the genome is non-coding, most of the genome consists of junk dna: The genome after 2005: most of the genome is transcribed, most of the genome appears to be transcribed into non-coding rnas (ncrnas) Basic processes of eukaryotic transcription: formation of the preinitiation. Complex of pic: binding of activators promotes the recruitment of co-activators and. Nucleosome remodeling complexes: chromatin is decondensed as a result of histone modifications and nucleosome eviction , gtps and rnapii are the recruited to form the pic or preinitiation. Micrornas and the control of translation rna interference. Control of gene expression vs. degradation by rna interference. Figure: regulation by microrna (control of gene expression) left side; regulation by dsrna (rna interference) right side.
