A gene that encodes a polypeptide is expressed in two steps. In this process, information flows from DNA → RNA → protein, a directional relationship known as the central dogma of molecular biology.
The Sequence Hypothesis defines biological information transfer as the residue-by-residue transfer of sequence information between nucleic acids and to proteins. This is commonly summarized as DNA RNA protein and is colloquially referred to as the Central Dogma.
The central dogma of molecular biology deals with the flow of genetic information within a biological system. It is often stated as "DNA makes RNA, and RNA makes protein", [1] although this is not its original meaning. It was first stated by Francis Crick in 1957, [2] [3] then published in 1958: [4] [5]

- *Amino acid synthesis* is the set of biochemical processes by which the amino acids are produced.
- RNA is dependent on DNA. So a change in DNA results in a change in RNA. Hope this helps!
- The two parts consist of transcription and translation. Transcription is the step where the genetic information from DNA is copied onto mRNA and se...
- In eukaryotic cells, transcription occurs in the nucleus, and translation occurs at the ribosomes in the cytoplasm. In prokaryotic cells and bacter...
The central dogma of molecular biology states that DNA contains instructions for making a protein, which are copied by RNA. RNA then uses the instructions to make a protein. In short: DNA → RNA → Protein, or DNA to RNA to Protein.
