These genes could have arisen by gene duplication.
<h3>What is gene duplication?</h3>
Gene duplication is the process of copying a section of DNA that codes for a gene. A retro transposition event or a recombination mistake are both potential causes of gene duplication. As a result, the duplicate gene coding may experience a significant number of modifications throughout time. This might prevent the gene from functioning or, in other situations, give the creature a benefit.
Gene duplication is a phenomenon that can happen through a variety of ways:
- Ectopic Recombination: Uneven crossing-over between misaligned homologous chromosomes during meiosis might result in duplications. A duplication at the exchange site and a reciprocal deletion are the results of this recombination.
- Replication Slippage: Short genomic sequences can be duplicated as a result of the replication error known as replication slippage. DNA polymerase starts copying the DNA during replication, but eventually the polymerase separates from the DNA, causing replication to stall. The replicating strand is incorrectly aligned when the polymerase reattaches to the DNA strand, which accidentally results in several copies of the same portion.
- Aneuploidy: When a single chromosome's nondisjunction causes an abnormally high number of chromosomes, this condition is known as aneuploidy. Aneuploidy is frequently damaging and frequently causes spontaneous miscarriages in mammals. Some aneuploid people can survive. For instance, human trisomy 21 causes Down syndrome but is not lethal.

"L<span>ieutenants" </span>responsible for an area of the prison, such as recreation or the shu.
The Secure Housing Unit or in short SHU, or isolation facility of a maximum security jail. While in fact, SHU can be utilized to portray any jail's isolation facility, it normally alludes to the unit of the Pelican Bay State Jail , situated in Folsom, California. The term SHU (articulated "SHOE") suggests the lodging unit itself and additionally the Draconian arrangements that contain its operations program. The objective of the program is to "screen, control and separate" around 1,200 of the most unstable and risky detainees in the California prison framework.
