The following points highlight the four main stages involved in synthesis of RNA. The stages are: 1. Binding of RNA Polymerase to DNA 2. Initiation of Transcription 3. Elongation of RNA chain 4. Termination of Transcription. Stage # 1. Binding of RNA polymerase to DNA: RNA polymerase binds to the “promoter site” on the DNA […]

In this article we will discuss about the non-genetic RNA. Non-genetic RNAs (tRNA, rRNA, mRNA) are synthesized on DNA templates through the process of transcription. The enzyme involved in transcription is “DNA dependent RNA polymerase”, or simply “RNA polymerase”. In E. coli, a single RNA polymerase catalyzes the synthesis of all kinds of RNAs. In […]

In this article we will discuss:- 1. Meaning of tRNA 2. Structure of tRNA 3. Initiator Transfer RNA. Meaning of tRNA: Transfer RNAs (tRNAs), also called “soluble RNAs” (sRNAs) are small molecules varying from 75 to 100 nucleotides in length. They carry amino acids and bring them to ribosomes to form the polypeptide chain. There […]
