Question and answer
he enetic material is duplicated?
Gene duplication is the process by which a chromosome or a portion of DNA is duplicated, resulting in an additional copy of a gene. Gene duplication is also referred to as chromosomal duplication or gene amplification. [ Duplication, which means to double, results in two identical genes. One or both of these genes may change over time through mutations to create two new different genes. Deoxyribonucleic acid (DNA) is unique to each organism and is the same in every cell making up that organism. Genes are sections of DNA that determine heredity and are housed in sections of the body known as
chromosomes. This makes up the genetic makeup of all organisms. Gene duplication usually occurs due to an error during meiosis. Meiosis occurs only in those cells that produce sex cells, such as sperm and eggs in humans. During meiosis, parent cells with two copies of the chromosomes produce four daughter cells that each only has one copy of each chromosome. This is so that when reproduction occurs, the cell that is created by the fusion of the sperm and egg will have the correct amount of DNA. ]
