Question

question 3 of 10
which type of mutation results in the formation of a protein with one
incorrect amino acid?
a. nondisjunction
b. frameshift
c. missense
d. silent

Explanation:

• Nondisjunction: Refers to the failure of chromosomes to separate properly during cell division, not directly related to a single incorrect amino acid in a protein.
• Frameshift: Caused by insertions or deletions that shift the reading frame, usually affecting multiple amino acids downstream, not just one.
• Missense: A point mutation where a single nucleotide change results in a codon that codes for a different amino acid, leading to a protein with one incorrect amino acid.
• Silent: A mutation that does not change the amino acid sequence of the protein (due to the degeneracy of the genetic code).

Answer:

C. Missense
