Homework Answers
1. The 2 types of mutations are Frameshift and insertion.
Frameshift mutation: It is caused due to insertion or deletion of base pairs in the DNA sequence results into the shift in the translational reading frame.
Insertion mutation: The addition of the extra nucleotide in a DNA sequence results in insertion mutation.
2. 3’-CAU-5’ is the anticodon on tRNA that corresponds to the mRNA codon 5’-GUA-3.
3. Exons or coding regions of the DNA end up being expressed in the protein.

QUESTION 11 A mutation in a bacterial gene generates a UGA stop codon in the middle of the mRNA coding for the protein product. A second mutation in the cell leads to a single nucleotide change in a tRNA that allows the correct translation of the protein. The altered tRNA translate the UGA as tryptophan. What nucleotide change has probably occurred in the mutant tRNA molecule? a. A mutation that changes the anticodon to 5-ACI O b. A mutation that...
