Question

Which mutation would NOT cause a change in an organism's phenotype?

Answer 1

A silent mutation does not produce a phenotype change. Explanation: In point mutations, a base pair of the DNA sequence is altered.

Step-by-step explanation:

Answer 2

B)TAT becomes TAC

Step-by-step explanation:

since thymine(T) pairs with adenine(A), thymine(T) is replaced with uracil(U) in the RNA and guanine(G) pairs with cytosine(C)

we can find the complementary codons for each strand

the codon for TAT is AUA which codes for methionine

the codon for TAC is AUG which also codes for methionine

that means the phenotype (methionine)remains unchanged for different genotypes(TAT and TAC)
