What is a chromosome deletion?
Chromosome is a chromosome mutation form. Chromosome mutations are caused by changes in the chromosome structure, unlike gene mutations, which are changes in the chemical composition of the chromosome. Chromosome mutations can in fact be detected by looking at DNA microscope. Mutations are DNA changes and can have negative or positive consequences.
In the nucleus of living cells, DNA is found in chains called chromosomes. Each type of organism has a specific number of chromosomes in its cells. For example, people have 46 chromosomes or 23 identical pairs. Along the chromosomes, the genes of cell properties and finally the organism specify the genes. Any mutation that occurs chromosome will affect this genetic information. Most of the time chromosomes can be found as long thin springs in the core. They are all around, so there are plenty of opportunities for interaction with other chromosomes and themselves.
During the chromosome deletion, the chromosome breaks in two different places. When the pieces join the singingT, the end pieces are attached and the middle part falls out. This middle piece of chromosome has now been deleted. Depending on what genetic information is done on a deleted piece of chromosome, the effects can be very serious. In some cases, this type of deletion may be deadly.
When the chromosome is deleted, the genes are lost on the cell. Because they are no longer part of the chromosome, transcription and translation processes will not go through, so suitable proteins will not be produced. Also, if the cell survives and replicates, this piece of DNA will not be copied, so all other cells will also have this mutation. This type of mutation will have a deep effect on how the body is constantly evolving. In fact, all the shortest chromosome delections are fatal to the cell.
depending on the size of the chromosome deletion can be seen by a microscope. Because chromosomes are found inThe same pairs, one from the father and one from the mother, both couples can be compared. If one of the couples is significantly deleted, it will look different from his partner. In this way, it is also possible to determine where the deletion occurred.
There are many different disorders of human chromosomes that are caused by chromosome deletion. There are also many different symptoms and severity of symptoms depending on which chromosome has been removed and how much. Examples of disorders caused by chromosomes are Cri-du-Chat and some cases of Duchenne muscle dystrophy.
