DNA is a nucleic acid that contains genetic instructions for the development and function of living organisms. I have learned some of the factors about DNA. DNA is not only a blueprint, but it also contains instructions to construct other components of the cells such as initiating the process of coping DNA into RNA molecule which then will be protein. Also, the structure of DNA is a double helix that is held by hydrogen bonds. UV light can damage DNA; and it has been estimated that in each human cell there are about 500 bases damage per day. The thing amazing me is our body works so hard to try to fix and replace most of the damages in the cell so that our body would remain functioning normally; additionally, there are thousands of mistakes in the process of making copies of our DNA into RNA and our body fixes almost all of them. Unfortunately, some of the mistakes are unrecognizable and unfixable by the cell; and the major damage/effect can eventually lead to fraternity illness such as cancers. In short, DNA is a complex molecule.
