Question
Change in the sequence of nucleotide in DNA is called as
Options
A.mutagen
B.mutation
C.recombination
D.translation
Solution
Alteration in the arrangement or amount of genetic material (DNA/genetic RNA) in a cell is called mutation.
Point mutations involve minor changes in the genetic material, while macro mutations involve large srgments of chomosomes, ′Frameshif mutations′ are the addition or deletion of nucleotide(not involving 3 base pairs) so that the reading frame of the RNA is shifted to left or right during translation.
