What is the central dogma of molecular biology?
Replied by Admin
The central dogma of molecular biology is the process of flow of genetic information from DNA to RNA to make a functional product which is a protein. It is described as the two-step process, transcription and translation, by which the information in genes flows into proteins: DNA ? RNA ? protein. Transcription and translation Steps: 1) RNA is made on a DNA template 2) RNA prossesing : The RNA transcript is spliced and modified to produce mRNA which moves to the cutoplasm 3) Amino acid attachment : The tRNA molecule picks uptheir amino acids 4) Initiation of translation : The first tRNA combines with the mRNA and ribosomal subunits to start polypeptide synthesis 5) Elogation : The polypeptide elongates as amino acidsare added 6) Termination : A stop codon signals release of the completed polypeptides and separation of ribosomal units...
