Central Dogma Steps
The Central Dogma of molecular biology is a concept that outlines the flow of genetic information within a biological system. The key steps in the Central Dogma are:
- Replication: The process in which DNA makes an identical copy of itself, ensuring the transmission of genetic information to the next generation during cell division.
- Transcription: The synthesis of RNA (specifically, messenger RNA or mRNA) from a DNA template. This step occurs in the cell nucleus and serves as a temporary copy of genetic information for protein synthesis.
- Translation: The process in which the information encoded in mRNA is used to build a corresponding protein. This occurs at the ribosomes in the cell cytoplasm, where transfer RNA (tRNA) molecules bring amino acids to the ribosome, allowing the formation of a polypeptide chain.
Central Dogma was a revolutionary and significant discovery in molecular biology. Because, for the first time it came with a clear picture of the information flow from DNA to phenotypes, which is related to the inheritance. Now we will discuss the each step of central dogma in detail.
Central Dogma of Molecular Biology
The Central Dogma of molecular biology was given by Francis Crick. The Central Dogma of genetics explains how genetic information flows from DNA to RNA to proteins within living organisms. It is a framework that describes how genetic information flows within a biological system. The Central Dogma outlines the sequential steps through which genetic information is transferred within a cell. In this article, we are going to discuss the central dogma steps in detail with its functions and further discoveries related to it.
