Lecture 2 outline: review regulation of genome expression, prokaryotic transcriptional regulation: genetic switches, trp operon, lac operon, note: tutorial 1pm-2pm tuesday, september 19th. Specific examples of how prokaryotic organisms regulate the expression of their genes, can be extended to eukaryotic organisms. Fundamental examples of how organisms in general regulate expression of their genomes. The expression of the genome needs to be regulated for development: not all genes are expressed at the same time or to the same extent, and vary depending on the external environment. The first product of genome expression is the transcriptome: the repertoire of rna molecules present in a cell at one particular time. Entire genome encodes all the genes required to make you and maintain you. Process of genome expression produces the transcriptome entire repertoire of rna molecules present in a cell at a particular time.
