Answer
(C) frameshift
Explanation
The question asks about the type of mutation resulting from the insertion or deletion of a nucleotide in a DNA sequence. The options are:1. Translocation: This refers to a chromosomal mutation where a chromosome segment is transferred to a new position on the same or another chromosome.2. Conversion: This is not a standard term used in the context of genetic mutations.3. Frameshift: This mutation occurs when nucleotides are inserted into or deleted from the DNA sequence, causing a shift in the reading frame of the genetic material.4. Inversion: This involves a segment of a chromosome being reversed end to end.The key to this question is understanding that the insertion or deletion of nucleotides alters the reading frame of the genetic code. This is known as a frameshift mutation because it shifts the grouping of the codons and hence changes the entire sequence of amino acids.
