Answer :

A silent mutation is a point mutation where a single base pair substitution does not alter the resultant amino acid sequence of the protein. It can occur both naturally and due to environmental conditions. Even though it doesn't change protein function, it might still affect protein synthesis and gene regulation.

A silent mutation is a type of mutation that does not cause a change in the amino acid sequence of the protein being expressed. This happens when there is a substitution of one nucleotide for another in the DNA sequence but the new codon still encodes for the same amino acid because of the degeneracy of the genetic code. Therefore, silent mutations do not result in a different protein product and are often considered nonfunctional or 'silent' because they don't appear to affect the phenotype of the organism.

Silent mutations usually occur as point mutations in the coding regions of a gene during DNA replication. However, these mutations can also occur spontaneously or in response to conditions in the body or the environment. Point mutations, such as silent mutations, affect a single base pair and include substitutions where one base is replaced by another. In silent mutations, the substitution does not alter the amino acid sequence of the protein resulting from gene expression.

While they don't directly alter protein function, silent mutations can have indirect effects on protein synthesis and gene regulation, influencing the evolutionary process and adding to genetic diversity within a population. Understanding the precise role and impact of silent mutations requires further research.
