geenimutaatio
Geenimutaatio refers to a permanent alteration in the DNA sequence that makes up a gene. These changes can occur spontaneously during DNA replication or be induced by external factors such as radiation or certain chemicals. Mutations can range in size from a single DNA building block, called a base pair, to a large segment of a chromosome that includes multiple genes.
The consequences of a geenimutaatio can vary widely. Some mutations have no observable effect on an organism,
The study of geenimutaatio is fundamental to understanding genetics, evolution, and disease. Scientists investigate mutations to
