Deoxyribonucleic Acid is a double stranded nucleic acid which has the genetic instructions employed in the functioning and development of all living organisms. It has bases that include cytosine, guanine, thymine, and adenine. Ribonucleic Acid on the other hand is a chain of single-stranded alternating ribose and phosphate units with the bases uracil, cytosine, guanine, and adenine attached to the ribose. Molecules of RNA are engaged in synthesis of protein and sometimes in the genetic information transmission. DNA is a medium of transmission and long-term storage of genetic information. However, the main Ribonucleic Acid job is to transmit the genetic code required for protein generation to the ribosome from the nucleus. This process protects the DNA safety by preventing it to leave the nucleus. The Deoxyribonucleic Acid deoxyribose sugar is stable in alkaline and lowly reactive due to C-H bonds. On the contrary, is not stable in alkaline and ribose sure is highly reactive due to C-OH bonds. DNA also contains smaller grooves in which the harmful enzymes can attach. This makes it less prone to enzyme attack. Ribonucleic Acidon the contrary contains bigger groove that make it prone to enzymes attack (Diffen, 2014).
Humans evolved with a DNA replication in the entire body and not a central repository to enhance the operations of different body organs. Deoxyribonucleic Acid is not only employed in reproduction, it is employed for all primary functions of cell that include the functioning of each body cell. Thus, replications make it easy to enhance cell functioning without having to consult any central repository. Central repository would demand that all body cells to wait the repose of the central repository to continue with their functioning. This would interfere with the cells efficiency as well as organs efficiency in performing their work in the body. For instance, skins would take longer than it is necessary to replace dead cells if the instructions of making new cells were in a central repository.
