and....
Genotype ratio Ww:ww
a. 2:1

c. 1:1
d. 3:1
Obtaining mRNA from the cell, then using reverse transcriptase enzyme to convert it into a stable cDNA (or copy of DNA) molecule for insertion into the bacterial cell.
A mutation occurs during the development of muscle cells but not in blood cells. Different genes are activated in muscle cells than in blood cells. Muscle cells experience different environmental influences than blood cells.
