Question

2.The new codon that you answered for #1 codes for which amino acid? Only give the three letter prefix for your answer.

Answer 1

A change in one base of the gene sequence is known as point mutation.

Explanation:

Question 2 is incomplete.

3. A mutation that only affects a single nucleotide of nucleic acid is known as Point Mutation.

In Point mutations there is substitution of one base for another.

Example:                TAT TGG CTA            

                               TAC TGG CTA

The  TAT changes to TAC which shows point mutation.

4. Yes. The point mutation have an effect on the outcome compared to the normal sequence.

When there is a change in one base of the gene it results into causing disease such as cancer, sickle cell anemia.
