What is the genomic DNA function?
Genomic DNA is genetic information that forms the genome, or a complete set of genetic information of the organism. DNA or deoxyribonucleic acid is a molecular chain composed of four different nucleotide bases called adenin, thymin, guanine and cytosine. The sequences of these bases in the DNA strands contain coded "instructions" that define most processes that occur during the development and daily function of the organism. Genomic DNA stores the entire coded "instruction manual". Usually there are cells in the form of chromosomes that are large, compact complexes formed by DNA and a number of regulatory proteins.
segments of both DNA encoding, which contains information used to produce proteins and other functional units, and non -coding DNA, which does not create a functional end product, exist in genomic DNA. DNA segment coding is generally rewritten to ribonucleic or RNA acid and translated into proteins. Proteins are highly abundant functional units in the body that are somehow napoJeny in almost all biochemical processes of the body. The function of most non -coding genomic DNA, most of which are distributed between some DNA segments, are not well known. Some of them work in different structural and regulatory roles, but scientists have not been able to attribute most of this to the exact function.
genomic DNA has a number of inheritance functions. Small deviations in the genomes of different people result in an individual with different features such as the height and color of the eyes. When parents reproduce themselves, their descendants receive some genomic DNA from the father, and some of them depend on the genetic information received from each parent. This is beneficial from the evolutionary perspective because it introduces greater diversity into the genome and ensures that at least some subset of the alarm will be genetically able to handle situations that may be unfavorable to survival.
different types of organisms and infectiousThe substances have different types of genomic DNA. For example, bacteria stores its DNA in a single circular chromosome, while human DNA is placed on 23 paired chromosomes. In particular, viruses show a large variation in their genomic DNA. The virus genome can be composed of an individual or double chain of DNA and can be linear or circular. Viruses tend to injure their DNA into host cells to take over the "machines" of these cells to make copies, allowing them to spread.
