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. WebMay 4, 2024 · Genetics is the scientific study of genes and heredity—of how certain …

WebSince all cells in our body contain DNA, there are lots of places for mutations to occur; however, not all mutations matter for evolution. Somatic mutations occur in non-reproductive cells and so won’t be passed on to offspring. For example, the yellow color on half of a petal on this red tulip was caused by a somatic.

WebSo it's not too surprising that prokaryotes can share genes by three other mechanisms: conjugation, transformation, and transduction. Transformation In transformation, a bacterium takes in DNA from its environment, often DNA that's been shed by other bacteria. In a laboratory, the DNA may be introduced by scientists (see biotechnology article ).
