Most gene contain the info needed come make useful molecules called proteins. (A few genes create regulatory molecules that assist the cell assemble proteins.) The trip from gene to protein is complex and tightly regulated within every cell. It consists of two significant steps: transcription and also translation. Together, transcription and also translation are well-known as gene expression.

You are watching: Genetic information usually flows in one specific direction

During the process of transcription, the details stored in a gene"s DNA is passed to a similar molecule referred to as RNA (ribonucleic acid) in the cabinet nucleus. Both RNA and DNA are consisted of of a chain of structure blocks referred to as nucleotides, however they have actually slightly different chemical properties. The type of RNA that includes the details for make a protein is referred to as messenger RNA (mRNA) because it dead the information, or message, native the DNA out of the nucleus right into the cytoplasm.

Translation, the second step in getting from a gene come a protein, takes location in the cytoplasm. The mRNA interacts v a specialized facility called a ribosome, which "reads" the succession of mRNA nucleotides. Every sequence of 3 nucleotides, dubbed a codon, normally codes because that one details amino acid. (Amino acids room the building blocks of proteins.) A kind of RNA dubbed transfer RNA (tRNA) assembles the protein, one amino mountain at a time. Protein assembly continues until the ribosomes encounters a “stop” codon (a succession of 3 nucleotides the does not code for an amino acid).

The flow of details from DNA to RNA come proteins is one of the fundamental principles of molecule biology. That is so important that it is sometimes dubbed the “central dogma.”


Through the procedures of transcription and translation, info from gene is provided to make proteins.
