Apr 8, 2025 · 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.

Mutation is the ultimate source of all genetic variation, providing the raw material on which evolutionary forces such as natural selection can act. Mutation can result in many different types of change in sequences. Mutations in genes can have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely.

Apr 28, 2017 · At the simplest level, a mutation is a change or transformation. In biology, mutations refer to changes in chromosomes and genes, which typically manifest physically. The effect of a mutation can depend on the region in which the …

2 days ago · A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.

May 24, 2022 · Genetic 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.

The meaning of MUTATION is a significant and basic alteration : change. How to use mutation in a sentence.

Mutation creates slightly different versions of the same genes, called alleles. These small differences in DNA sequence make every individual unique. They account for the variation we see in human hair color, skin color, height, shape, behavior, and susceptibility to disease.

A mutation is a permanent, heritable change in the nucleotide sequence or the process by which such a change occurs in a gene or in a chromosome. There are two major types of mutations: small-scale and large-scale.

May 8, 2019 · Gene mutation refers to random alterations in DNA that occur in somatic and reproductive cells, often during replication and division. Effects of gene mutation can range from silent expression to self-destruction. Gene mutation examples can include genetic disorders like sickle cell anemia.

Jan 14, 2025 · Genetic mutations are changes in the DNA sequence that can significantly affect an organism’s health and development. These alterations can occur spontaneously or be …
