How might a gene mutation be silent, with no observable effect on a cell or an organism? Question 9 options:

A)

Several codons are stop codons. A gene mutation that inserts a stop codon when only a few amino acids remain in the peptide sequence would have no observable effect on the cell or the organism.

B)

Many proteins are superfluous to the function of a cell. A gene mutation in a gene that encodes an unnecessary protein would have no observable effect on the cell or the organism.

C)

Codons are complementary to anticodons in tRNA. A gene mutation that changes a codon to its anticodon would have no observable effect on the cell or the organism.

D)

Many amino acids are encoded by multiple codons. A gene mutation that encodes the same amino acid would have no observable effect on the cell or the organism.
