Junk Deoxyribonucleic Acid - Essay Example

Genes are responsible for the formation of proteins. Numerous proteins are being synthesized in the body to fulfill diverse metabolic, structural, and physiological requirements of the organism. Human beings contain a plethora of genes and the human genome has been successfully deciphered. Initially, when it was discovered that DNA is present in the chromosomes, and the entire chromosome is made up of genes that code for proteins. However, with subsequent findings, now it is established that less than 10% of human chromosomes are composed of genes.

The rest was termed "junk DNA". With time "junk DNA" or the "noncoding DNA" has been considered to play significant regulatory roles in modulating the performances or actions of the "coding DNA". Knowledge about this relationship is highly imperative as it depicts the behavior of genes in the artificial insertion of unknown genes. Only a few studies could understand the role of this relationship in structural formation, but an understanding of the regulation is yet to interpret. Since non-coding genes were not assigned any function but are present in the cell carries a deep meaning.

If they do not play any role, the sequence of syllables should be random, which is not. This is a great subject of research as the "junk DNA" possess some kind of coded information which scientists are trying to decode. Potentially, some of these genes are thought to possess repetitive patterns which may be associated with cancer.
