Question

A point mutation occurs when a single nucleotide gets replaced by a different one.

Answer 1

It's true, a point mutation occurs when a single nucleotide gets replaced by a different one.

A point mutation occurs when one nucleotide gets replaced by a distinct one. A chromosomal mutation in which a segment is missing is called a deletion. In base excision repair, a whole segment of DNA is removed and resynthesized. Spontaneous mutations that occurs in somatic cells will be transmitted to offspring.

A point mutation is a genetic mutation where one nucleotide base is modified, inserted or deleted from a DNA or RNA sequence of an organism's genome.

Point mutations have a range of effects on the downstream protein product consequences that are moderately predictable based upon the specifics of the mutation.
