Frameshift Mutation- Definition, Causes, Mechanism, Applications, Examples

Frameshift Mutation

Frameshift mutation definition A frameshift mutation is a type of genetic mutation resulting from the alteration of a number of nucleotides in DNA sequences that are not multiple of three. Frameshift mutation occurs as a result of a change in the reading frame of the sequence. Since the codons for gene expression occur in the form of triplets, the difference …

Silent Mutation

What are Silent mutations? Silent mutations are mutations where the changes in the nucleotide sequence of DNA do not produce any observable effect on the organism. The change in nucleotide doesn’t produce a change in the amino acid sequence or the structure and function of the protein. Silent mutations are also termed neutral mutations as these do not cause any …

Nonsense Mutation- Definition, Causes, Mechanism, Applications, Examples

Nonsense Mutation

Nonsense mutation definition A nonsense mutation is a type of mutation where a premature stop codon is added to a sequence which hinders the further translation of the protein-coding gene. The nonsense mutation is classified as a loss-of-function change where the mutation impairs the production of a particular protein. Nonsense mutation, like most other mutations, can have a range of …

Missense-Mutation

Missense mutation definition A missense mutation is a type of mutation where the alteration of a nucleotide base in a gene sequence results in the translation of different amino acids in the protein. A missense mutation is a type of nonsynonymous substitution in a DNA sequence, indicating that the mutation results in some kind of effect on the resulting sequence. …

Point mutation- Definition, Causes, Mechanism, Types, Examples, Applications

Point mutation

Point mutation definition Point mutation is a type of genetic mutation where one of the base pairs in the DNA sequence is altered either by insertion or deletion. Point mutation, as the name indicates, occurs at a particular point of the DNA sequence as a result of changes in one particular base pair. Usually, point mutations arise as a result …

Types of Mutations

The mutation is a process that produces a gene or chromosome that differs from the wild type (arbitrary standard for what “normal” is for an organism). The mutation may result due to changes either on the gene or the chromosome itself. Thus, broadly mutation maybe: Gene mutation where the allele of a gene changes. Chromosome mutation where segments of chromosomes, …
