A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.hese changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if a mistake is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed on to the next generation.
2- Chromosomal mutations are changes in the structure or the numbers of chromosomes (a gain or loss). Gene mutations involve changes in the nucleotide sequence of the DNA molecule. 3-A gene mutation is a permanent change in the DNA sequence that makes up a gene. gene mutation can be acquired throughout life or it is genetic ex sickle cell anemia chromsome mutations have more pronounced effects and are due to a change in the number â¦ of chromosomes or a change in the structural effect that are inherited.. ex downs syndrom. 3 people found this useful.
