How do genetic mutations affect an organism

WebKey points: A mutation is any change to the nucleotide sequence of a DNA molecule. Some mutations arise as DNA is copied. Others are due to environmental factors. A mutation in a gene can change the structure and function of the protein encoded by that gene. This, in turn, can affect an organism’s traits. Mutations can be considered harmful ... WebSome mutations don’t have any noticeable effect on the organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but does not affect the amino acid sequence of the protein. Other mutations have a noticeable effect, but one that ...

WebWithout genetic variation, some key mechanisms of evolutionary change like natural selection and genetic drift cannot operate. There are three primary sources of new genetic variation: Mutations are changes in the information contained in genetic material. (For most of life, this means a change in the sequence of DNA.) A single mutation can have a WebMutations result in different forms of the same gene. These different forms are called alleles. For example, eye color is coded by different alleles of the same gene. When the DNA's instructions are read by the cell's machinery, these differing alleles can cause variations in the traits of organisms. WebJun 8, 2024 · Mutations are changes to an organism’s DNA that create diversity within a population by introducing new alleles. Some mutations are harmful and are quickly eliminated from the population by natural selection; harmful mutations prevent organisms from reaching sexual maturity and reproducing. regina judge
