Question

mutation occurs when the changes do not alter the overall amino acid production. silent no answer text provided. missense nonsense question 5 4 pts mutation - new nucleotide changes a codon that specifies a stop codon - protein production stops early. missense no answer text provided. silent nonsense

Explanation:

• Silent mutation: A silent mutation occurs when a change in the DNA sequence (usually a single - nucleotide substitution) does not result in a change in the amino acid sequence of the protein. This is because the genetic code is degenerate, meaning that multiple codons can code for the same amino acid.
• Nonsense mutation: A nonsense mutation is a type of mutation where a change in a single nucleotide results in the formation of a premature stop codon. When this happens during translation, the ribosome encounters the stop codon earlier than it should, and protein production stops prematurely.
• Missense mutation: A missense mutation is a single - nucleotide substitution that results in a codon that codes for a different amino acid.

For the first blank:
Since the description is about a mutation that does not alter the overall amino acid production (due to the degenerate nature of the genetic code), it is a silent mutation.

For the second blank:
Since the description is about a mutation that changes a codon to a stop codon and causes early protein production termination, it is a nonsense mutation.

Answer:

First question: silent
Second question: nonsense
