Which statement explains why the structure of sickle cells differs from normal red blood cells? a. The gene mutation affected protein synthesis.
b. The gene mutation prohibited DNA replication.
c. The gene mutation inhibited the cell's ability to produce tRNA.
d. The gene mutation affected the cell's ability to produce ATP.​

A. the gene mutation affected protein synthesis

Explanation:

Basically, sickle cell results due to point mutation (change in one nucleotide) in DNA, which in turns affects the mRNA produced and finally the protein made from that mRNA is affected. I have listed a helpful image below which shows that the mutation actually results in formation of an undesired protein which causes sickle cell to occur.
