Explaine the central dogma of biomelocular

Answer 1

The central dogma of molecular biology is a principle that outlines the flow of genetic information within a biological system. The central dogma states that genetic information is stored in the DNA of an organism, which is then transcribed into messenger RNA (mRNA) in a process called transcription. The mRNA is then translated into proteins in a process called translation.

In summary, the central dogma of molecular biology can be broken down into three main steps:

1. DNA replication: DNA serves as the genetic blueprint for an organism and is responsible for storing all the genetic information needed for cellular functions.

2. Transcription: The genetic information stored in DNA is transcribed into mRNA by an enzyme called RNA polymerase. This process occurs in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells.

3. Translation: The mRNA transcript is then translated into proteins by ribosomes, which interpret the sequence of nucleotides in the mRNA and assemble the corresponding amino acids into a protein chain.

Overall, the central dogma of molecular biology describes the flow of genetic information from DNA to RNA to protein, highlighting the interconnected processes that govern gene expression and protein synthesis in living organisms.
