WebMay 18, 2024 · 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 by damage to chromosomes (changes in the number or structure of entire chromosomes, the structures that carry … WebDec 22, 2006 · Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein. That's possible because proteins are encoded by "triplets" of nucleotides, each responsible for adding a particular amino acid to the protein chain.

WebA mutation is a change in DNA, the hereditary material of life. An organism’s DNA affects how it looks, how it behaves, and its physiology. So a change in an organism’s DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur. WebMost changes to a person’s DNA don't affect their genetic makeup and won’t lead to any health problems, but some mutations cause genetic conditions that could affect your health. There are thousands of possible genetic mutations that could occur when your cells divide and replicate. Two types of genetic mutations include: Germline mutations.
