3. Below is the nitrogen base sequence for a strand of DNA. UAU-UGG-GUG-CUA
A mutation occurs and the nitrogen base cytosine is
replaced with adenine in the sequence above. Using the
amino acid chart below, determine if a detectable change in
protein synthesis has occurred?

A No, the protein will remain the same despite the
change in nitrogen bases.
B Yes, Leucine is changed to Tyrosine.
C Yes, Leucine is changed to Isoleucine.
D Yes, Valine is changed to Isoleucine.
