Analysis of DNA sequences from two individuals of the same species results in a greater estimate of genetic variability than does analysis of amino acid sequences from the same individuals because:____.
a. Different DNA sequences can code for the same amino aciid.
b. Some amino acid variations cannot be detected by protein electrophoresis.
c. DNA sequencing is a more reliable technique than protein electrophoresis.
d. Proteins are more easily damaged than is DNA.
e. DNA is more heat-sensitive and therefore varies more.
