Question
Which type of mutation results when bases are added to a gene?A.MissenseB.FrameshiftC.SilentD.Nondisjunction
Solution
The type of mutation that results when bases are added to a gene is B. Frameshift.
Here's why:
A. Missense mutation: This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene.
B. Frameshift mutation: This type of mutation occurs when the addition or loss of DNA bases changes a gene's reading frame. A reading frame consists of groups of 3 bases that each code for one amino acid. Frameshift mutations are generally much more serious and more likely to lead to a nonfunctional protein.
C. Silent mutation: This is a change in the sequence of DNA bases but it does not result in a change in the amino acid at that position in the protein.
D. Nondisjunction: This is not a type of mutation in the DNA sequence, but rather an error in cell division that results in cells with an abnormal number of chromosomes.
