Mutation, Repair, and
I. POINT MUTATIONS
DeVries coined the term mutation back in 1901 to describe
variation in a plant, the evening primrose.
Some mutations in this plant were chromosomal aberrations,

VIRUSES (CHAPTER 5)
. There are several different methods that
bacteria and/or the phages that attack them use
to undergo exchange of gen
I. ALLELES (CHAPTER 6)
. Mendel gave us basic genetic
transmission laws, but these need to be
modified because alleles act and interact
in various ways to produce phenotypes.
. So there are various modifications o
Proteins and Their Synthesis
I. GENES AND PROTEINS
A. Genes Make Proteins.
. It was known from early experiments that the primary
product of genes was proteins, especially enzymes.
. One-gene-one-polypeptide hypothesis gave this insight.
The Dynamic Genome:
A. Non-Fixed Loci.
. Starting back in the 1930s, geneticists began to get
some evidence that genes were not fixed to certain
loci and could sometimes move around in the

The Genetic Control of
GENETICS OF DEVELOPMENT
In the early days of Drosophila genetics, they found occasional
developmental mutants that produced flies with 4 wings instead of
This mutant was called bithora

A. Complexity. Eukaryotic regulation of gene expression
is much more complicated than prokaryotic regulation.
Reasons for this:
there is a greater amount of DNA which is complexed
