What is a Genetic Mutation? Definition & Types - Cleveland Clinic
https://my.clevelandclinic.org/health/body/23095-genetic-mutations-in-humans
WEBGenetic mutations are changes to your DNA sequence that happen during cell division when your cells make copies of themselves. Your DNA tells your body how to form and function. Genetic mutations could lead to genetic conditions like cancer, or they could help humans better adapt to their environment over time.

WEBApr 5, 2024 · Mutation, an alteration in the genetic material (the genome) of a cell of a living organism or of a virus that is more or less permanent and that can be transmitted to the cell’s or the virus’s descendants. The genomes of organisms are all composed of DNA, whereas viral genomes can be of DNA or RNA.

WEBMay 18, 2018 · A genetic disorder is a disease caused in whole or in part by a change in the DNA sequence away from the normal sequence. Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of gene mutations and environmental factors, or …

WEBSome people have changes in the nucleotides of a gene, which are known as variants (or mutations ). For example, one nucleotide ‘letter’ might be switched for another, or one or more letters might be missing, when compared to most other people’s genes. Gene variants can have different effects on the proteins they code for. For example:
