How might a gene mutation be silent, with no observable effect on a cell or an organism? A. Codons are complementary to anticodo
ns in tRNA. A gene mutation that changes a codon to its anticodon 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. 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. 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.
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
Explanation:
If gene mutation does not change code (gene still encodes for the same amino acid), the same protein with its function will be produced. This is called synonymous mutation.
Silent mutations might also occur when codon is altered to produce an amino acid with similar function as previous (e.g. leucine to isoleucine) so that the function of protein is not significantly changed.
Sterilization technique is a method in which low temperatures is used for controlling of microorganisms growth which causes infection in food materials, while in microbicidal method, compounds are used to decrease the growth of harmful microorganisms in a substances which causes infection. Wood tar is the example of microbicidal compound.
