17. How might a gene mutation be silent, with no observable effect on a cell or an organism?

A. 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.
B. 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.
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. 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.

Final answer:

Silent mutations are caused by gene mutations that change codons to encode the same amino acid, having no impact on the protein product.


Explanation:

Silent mutations occur when a gene mutation changes a codon to another codon that encodes the same amino acid. This is due to the redundancy in the genetic code where most amino acids have multiple codons. As a result, these mutations have no effect on the protein product. Detecting silent mutations typically requires sequencing the gene or its mRNA.
