1. Over the course of these chapters, we have read about the many contributions by various figures that have all played a significant role in
determining that DNA is the genetic blueprint. Please list any four of these figures and define their contributions. Please include what exactly their
findings helped determine.
2. In mammalian females, one of the two X chromosomes in each cell is randomly inactivated during embryonic development. Please explain this
process in brief. Why is this important (think about this from a genetic disorder point of view). What is the inactivated structure called?
3. In 1952, Alfred Hershey and Martha Chase showed that DNA is the genetic material of a phage known as T2. They designed an experiment
showing that only the DNA of the T2 phage, and not the protein, enters an E. coli cell during infection. Please summarize their experimental
approach in as much detail as possible. What were their findings? Do you agree with their findings?
