In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.n this situation, translation begins at the 5' end of the mRNA while the 3' end is still attached to DNA. In all types of cells, the ribosome is composed of two subunits: the large (50S) subunit and the small (30S) subunit (S, for svedberg unit, is a measure of sedimentation velocity and, therefore, mass).
Translation is the process of converting the genetic information in the mRNA strand to the form of a protein. The basic unit of this genetic information is a codon. Earlier, we described a codon as a sequence of three nucleotide bases that specifies a particular amino acid. Codon recognition describes the process of matching codons to the correct amino acids. Codons are read down the length of the mRNA strand and translated into an appropriate polypeptide chain.
