Detailed explanation-1: -A point mutation is a genetic mutation where a single nucleotide base is changed, inserted or deleted from a DNA or RNA sequence of an organism’s genome. Point mutations have a variety of effects on the downstream protein product-consequences that are moderately predictable based upon the specifics of the mutation.

Detailed explanation-2: -An insertion changes the DNA sequence by adding one or more nucleotides to the gene. As a result, the protein made from the gene may not function properly. A deletion changes the DNA sequence by removing at least one nucleotide in a gene.

Detailed explanation-3: -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.

Detailed explanation-4: -Nonsense Mutation A nonsense mutation occurs in DNA when a sequence change gives rise to a stop codon rather than a codon specifying an amino acid. The presence of the new stop codon results in the production of a shortened protein that is likely non-functional.

Detailed explanation-5: -Point Mutation A point mutation occurs in a genome when a single base pair is added, deleted or changed.
