Detailed explanation-1: -Point mutation, also known as substitution, is a type of genetic mutation where the nucleotide base is inserted, deleted, or changed in the DNA or RNA of the genome of an organism. These have a variety of effects on the products, where the consequences are predictable with the specific mutation.

Detailed explanation-2: -A genetic alteration caused by the substitution of a single nucleotide for another nucleotide. Also called point variant.

Detailed explanation-3: -A type of substitution mutation, a point mutation, occurs which a single nucleotide is substituted. This can be seen in the image below. Importantly, a substitution mutation results in DNA of the same length. It does not add or subtract from the number of nucleotides in the sequence.

Detailed explanation-4: -Substitution, as related to genomics, is a type of mutation in which one nucleotide is replaced by a different nucleotide. The term can also refer to the replacement of one amino acid in a protein with a different amino acid.

Detailed explanation-5: -Substitution. A substitution mutation occurs when one base pair is substituted for another. For example, this would occur when one nucleotide containing cytosine is accidentally substituted for one containing guanine.
