Central Dogma of Molecular Biology
- The central dogma of molecular biology explains the flow of genetic information, from DNA to RNA, to make a functional product, a protein.
- The central dogma suggests that DNA contains the information needed to make all of our proteins, and that RNA is a messenger that carries this information to the ribosomes.
- The ribosomes serve as factories in the cell where the information is ‘translated’ from a code into the functional product.
- The process by which the DNA instructions are converted into the functional product is called gene expression.
- Gene expression has two key stages - transcription and translation.
- In transcription, the information in the DNA of every cell is converted into small, portable RNA messages.
- During translation, these messages travel from where the DNA is in the cell nucleus to the ribosomes where they are ‘read’ to make specific proteins.
- The central dogma states that the pattern of information that occurs most frequently in our cells is:
- From existing DNA to make new DNA (DNA replication)
- From DNA to make new RNA (transcription)
- From RNA to make new proteins (translation).
- Reverse transcription is the transfer of information from RNA to make new DNA, this occurs in the case of retroviruses, such as HIV.
- It is the process by which the genetic information from RNA is assembled into new DNA.
