A genetic mutation occurs due to a change in a single nucleotide base, either inserted or deleted from the genetic material (DNA or RNA) sequence, which represents the mutation called a point mutation.
It can take place by the substitution of the single nucleotide sequence in DNA or RNA in the genome of the organism, it is also known as substitution mutation.
Sickle cell anemia is an example of the point mutation that takes place due to a change in a single nucleotide sequence.
