A mutation occurs in a nucleotide when there is a change in its structure, which can involve alterations in the nitrogenous base (adenine, thymine, cytosine, or guanine), the sugar (deoxyribose in DNA), or the phosphate group. Most commonly, mutations are associated with changes in the nitrogenous base, leading to substitutions, insertions, or deletions that can affect the genetic code. These changes can result from errors in DNA replication, environmental factors, or chemical exposure.

How does a mutation occur?

A mutation is a change in the DNA sequence that can arise spontaneously during cell division, due to errors in DNA replication or exposure to environmental factors like radiation or chemicals. Mutations can also be inherited from parents and can occur in different ways, such as single nucleotide changes, insertions, deletions, or rearrangements of DNA segments.


What are known as gene mutations and occur at a single point in the DNA sequence?

Gene mutations that occur at a single point in the DNA sequence are called point mutations. These mutations can involve substitutions of one nucleotide for another (missense mutation), insertion of an extra nucleotide (insertion mutation), or deletion of a nucleotide (deletion mutation). Point mutations can have various effects on the resulting protein, ranging from no impact to severe functional changes.
