Homework Answers
As we know there are multiple codons for a single amino acid in many cases, however, I have used only one codon for each amino acid, so different people can have different mRNA sequence.
a)
b) From the figure, it is clear that 4th nucleotide "A" is being deleted and "G" is being inserted at the 15th position from the deleted nucleotide.
