What is the duplication of the gene?
The duplication of the gene is a process that duplicates chromosome or part of the DNA, resulting in another copy of the gene. The duplication of the gene is also referred to as chromosomal duplication or amplification of the gene. Duplication, which means double, results in two identical genes. One or both these genes can change over time through mutations and create two new different genes. The genes are DNA cuts that determine inheritance and are located in parts of the body known as chromosomes. This forms the genetic composition of all organisms. Meiosis occurs only in those cells that produce sex cells such as sperm and eggs in humans. During meiosis, birth cells with two copies of chromosomes produce four daughter cells, each with only one copy of each chromosome. This is so that when the CTion reprodel occurs, the cell that is created by the fusion of semen and eggs will have the right amount of DNA.
During meiosis, the genes are likely to exceed when chromosomes are exceeded andThere will be a recomb. Chromosome sources can break and re -connect to the opposite chromosome, so genetic information moves from one chromosome to another. If it is not equal to the recomination, or it happens with a different amount of DNA, duplication may occur.
Another way to duplicate the gene may occur if the whole chromosome is replicated twice. This error will lead to one of the daughter cells to have another copy of the chromosome and all other genetic material. If this cell is connected to another cell during reproduction, it may or may not result in a viable zygot.
The latest way to duplicate the gene can be via retrotransposition. During the retrotransposition, the DNA sequence is copied to RNA and then back to the bottom instead of being translated into proteins. This results in further copies of this DNA are present in a cell that can be re -attach to chromosomes that are already present. Any genes found along these DNA sequences will be duplicated in this process.
When genes duplicate, a copy of the original is called the Paralog gene. It is possible that both or one of the genes mutate, but it is not always. During the mutation process or changes, genes can obtain functions that differ from the original gene.
The original gene can also mutate and create two genes that differ from the original gene before duplication. The duplication of the gene is considered to be the driving force in the formation of new genes and thus changes in normal biological processes. Duplication processes of gene and mutation play key roles in evolution.
