Mutation: GATE (Biotechnology)

In biology, a mutation is the alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA.

Overview of Mutations

Spontaneous mutations are the result of errors in natural biological processes, while induced mutations are due to agents in the environment that cause changes in DNA structure.

Spontaneous and Induced Mutations ( Part 1)

Spontaneous and Induced Mutations ( Part 2)

In a point mutation, one nucleotide is swapped out for another. Therefore, the mutation occurs at a single point or location within the DNA strand. Point mutations usually only affect the codon that contains the altered nucleotide. Frameshift mutations are due to either insertions or deletions of nucleotides.
