Answer:
The six codons for arginine are the following:
GCA, GCG, GCT, GCC, TCT, TCC
A) Considering the individual bases in each codon, three mutations are possible at each base position. Hence, 3 × 3 × 6 = 54 mutations are possible.
B) Considering the mutations at the 3rd base: 3 × 4 + 1 × 2 = 14 of these mutations are silent mutations.
C) Lysine codons are the following:
TTT, TTC
There are two possible mutations that can give a lys codon.
