Challenges to the Modern Synthesis Stephen Jay Gould, Nils Eldredge,

DNA

Transcription

Translation Notion of “gene expression”

Question: Why aren’t “identical twins” identical?

Epigenetics From Wikipedia: “Epigenetics is the study of heritable changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence.” Is epigenetics why cloned animals don’t fare well?

Genetic regulation

Genetic Switches (in “non-expressed” regions)

Genetic Regulatory Networks

Random Boolean Networks as models of genetic regulatory networks
