Detailed explanation-1: -Changes to short stretches of nucleotides are called gene-level mutations, because these mutations affect the specific genes that provide instructions for various functional molecules, including proteins. Changes in these molecules can have an impact on any number of an organism’s physical characteristics.
Detailed explanation-2: -A mutation is a change in a genetic sequence. Mutations include changes as small as the substitution of a single DNA building block, or nucleotide base, with another nucleotide base.
Detailed explanation-3: -A frameshift mutation is a genetic mutation caused by a deletion or insertion in a DNA sequence that shifts the way the sequence is read. A DNA sequence is a chain of many smaller molecules called nucleotides.
