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 […]

In this article we will discuss about Heterogeneous Nuclear RNA (hnRNA). Unlike prokaryotic mRNA, eukaryotic mRNAs are monocistronic. The primary transcript in eukaryotes is much larger than the mature mRNA and is called Heterogeneous nuclear RNA (hnRNA). It contains unique sequences and has about 10 times as many sequences as the mature mRNA. hnRNA undergoes […]
