|
|
Gene mutations may lead to evolution if it gives the organism an advantage over other organisms in the population
|
|
|
A mutated gene can produce a shorter protein that a normal gene by changing a codon sequence to a stop codon
|
|
|
mutation in a noncoding region could also interfere with the regulation of gene expression, keeping a protein from being produced or causing it to be produced all the time.
|
|
|
If this change happens in the active site of an enzyme, the enzyme may not be able to bind to its substrate
|
|
|
If the substituted amino acid differs from the original one in size or polarity, the mutation could affect protein folding and thus possibly destroy the protein’s function.

Detailed explanation-1: -Mutations can be of many types, such as substitution, deletion, insertion, and translocation.
Detailed explanation-2: -Missense: A missense variant is a type of substitution in which the nucleotide change results in the replacement of one protein building block (amino acid) with another in the protein made from the gene. The amino acid change may alter the function of the protein.
Detailed explanation-3: -Mutations are changes in a DNA sequence, and they can occur due to radiation or other types of DNA damage. If mutations occur in the part of a gene that encodes a protein (the coding region of a gene), they can change the amino acid sequence of that protein.
Detailed explanation-4: -Missense Mutation A missense mutation is a DNA change that results in different amino acids being encoded at a particular position in the resulting protein. Some missense mutations alter the function of the resulting protein.
