What is Central Dogma?

central_dogmacentral dogma

The central dogma is the main thesis of molecular inheritance. It states that DNA makes RNA which makes protein. DNA is copied to DNA by the process of DNA replication. The DNA information can be copied into mRNA by the process of transcription. The proteins can now be synthesized using the information in mRNA as a template in the process of translation.

What is a nucleic acid?

It is a naturally occurring chemical compound that is capable of being broken down to yield phosphoric acid, sugars, and a mixture of organic bases (purines and pyrimidines). Nucleic acids are the main information carrying molecules of the cell. It does so by directing the process of protein synthesis and by determining the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses. RNA is the genetic material of certain viruses but it is also found in all living cells where it plays an important role in certain processes such as the making of proteins.
