Q. A mutation in a gene that codes for a polypeptide results in a variant polypeptide that lacks the last three amino acids. What type of mutation is this?<\/p>\n\n\n\n
(A) Synonymous mutation<\/p>\n\n\n\n
(B) Nonsense mutation<\/strong><\/p>\n\n\n\n (C) Missense mutation<\/p>\n\n\n\n (D) Silent mutation<\/p>\n\n\n\n Ans: Nonsense mutation<\/strong><\/p>\n\n\n\n Solution:<\/p>\n\n\n\n A nonsense mutation is a type of mutation in which a nucleotide change in the DNA sequence results in the formation of a premature stop codon in the mRNA. This premature stop codon leads to the termination of translation before the entire polypeptide is synthesized. As a result, the resulting polypeptide will be shorter and likely non-functional due to the missing amino acids.<\/p>\n\n\n\n In the scenario described, the mutation causes the gene to produce a variant polypeptide that lacks the last three amino acids. Since the mutation introduces a premature stop codon, it is consistent with a nonsense mutation.<\/p>\n","protected":false},"excerpt":{"rendered":" Q.
