A missense mutation in the nucleotide sequence of a gene definitely has the effect of: A) The substitution of an amino acid in the protein encoded by the gene B) The production of a protein longer than normal C) The production of a protein shorter than normal D) The death of the cell in which the mutation occurred E) The failure to produce the protein encoded by the gene
Question
A missense mutation in the nucleotide sequence of a gene definitely has the effect of:
A) The substitution of an amino acid in the protein encoded by the gene B) The production of a protein longer than normal C) The production of a protein shorter than normal D) The death of the cell in which the mutation occurred E) The failure to produce the protein encoded by the gene
Solution
A missense mutation refers to a change in one nucleotide in a gene that results in the substitution of a different amino acid in the protein that the gene encodes. This can alter the function of the protein, but it does not necessarily lead to the production of a longer or shorter protein, the death of the cell, or the failure to produce the protein. Therefore, the correct answer is:
A) The substitution of an amino acid in the protein encoded by the gene
