The Relevance of DNA & Environment

Bumgye M.S 20902 Jiyou Kwon

 

     DNA is an abbreviation of “deoxyribonucleic acid”, and it was discovered by James Watson and Franeis Crick. DNA is self-replicating material that’s in every living organism. It contains the instructions needed for organisms to develop, grow, survive, and reproduce. It has four types of nitrogens ; adenine, cytosine, guanine, and thymine and works itself into that single-stranded molcule called RHA.

 

     DNA has its various types. EDNA(Environmenmental DNA) is that released from an organism into the environment. Recent research has shown that the DNA of a range of aquastic organisms can be detected in water. In aquatic environments, DNA is dilated and distributed in the water where it persists for 7-21days, depending on the conditions. However, the DNA of organisms once trapped in sendiments can be preserved for thousand of years.

 

     Even if most of the people don’t really know about the EDNA’s presense, this kind of scientific and environmental source will be needed by the future society, development, and ofcourse in the whole science.
