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 eukaryotes, there are at least [...]
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 are 20 amino acids but [...]
In this article we will discuss about the meaning and structure of nucleic acids. Meaning of Nucleic Acids: Nucleic acids are a long chain polymers of nucleotides which are joined together by means of phosphodiester linkages. In phosphodiester bonds, one phosphoric acid molecule forms bonds with the 3' carbon of one pentose molecule as well as with the 5' carbon [...]
