|2||Information flow in the reverse direction - from DNA to RNA to protein (the central dogma)
Review of regulatory circuits and introduction to the concept of evolutionary genomics
Key Issues: DNA replication and repair errors lead to mutations. Loss of mismatch repair leads to a hyper-Rec phenotype, which facilitates horizontal gene transfer (antibiotic resistance, etc.)
McAdams, Harley H., et al. "The Evolution of Genetic Regulatory Systems in Bacteria." Nature Reviews (Genetics) 5 (March 2004): 1-9.
This paper on evolution of genetic regulatory systems will also introduce the third major topic of the course, chemotaxis; Also read the section on DNA structure and base hydrogen bonding properties from a good biochemistry book.
