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

B)TAT becomes TAC

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)

because it is and it's just life man

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.
