Question

PLEASE HELP!! BIO!
Using the information in the table below, determine the amino acid sequence that is coded for by the mRNA sequence: AUG -UCU-GAU-UGG-UAC
Situation A: Using the information in the table, determine the first four amino acids coded for if a mutation occurs in the DNA sequence from part (a) which changes the sixth base (read left to right) to C making the new DNA sequence TAC-AGC-CTA-ACC-ATG

What type of mutation occurred in the previous question where one base was changed ?

Answer 1

Answer:

a) Met - Ser - Asp - Trp - Tyr

b) Met - Ser - Asp - Trp

Neutral mutation (which is caused by a type of single gene mutation called a substitution mutation)

Explanation:

After the substitution of A to C, the amino acid codded for stays the same so this is known as a neutral mutation.
