What are some examples of gene mutations?

Question

Penelope Adams · Accepted Answer

Frame shifts, deletions, and base substitutions are examples of gene mutations.

Frameshift mutations: Deletions of a base can result in a frameshift, which can cause the production of different amino acids by altering the triplet sets being translated. For instance, if the frame shifted from UGAAGGCGA to GAAGGCGAU.

undefined Some examples of gene mutations include:

1. Point mutations: Single nucleotide changes, such as substitutions, insertions, or deletions.
2. Frameshift mutations: Insertions or deletions of nucleotides that shift the reading frame of the genetic code.
3. Chromosomal mutations: Changes in the structure or number of chromosomes, such as deletions, duplications, inversions, or translocations.
4. Silent mutations: Nucleotide changes that do not result in an amino acid change due to the degeneracy of the genetic code.
5. Nonsense mutations: Point mutations that create a premature stop codon, leading to truncated or non-functional proteins.
6. Missense mutations: Point mutations that change a single amino acid in a protein sequence, potentially altering its function.
7. Insertion and deletion mutations: Addition or removal of one or more nucleotides, causing a shift in the reading frame or loss of genetic material.
