In this article we will discuss about the process of biosynthesis of RNAs. The polymerization of ribonucleosides-5'-triphosphates to RNA is a process called transcription, because the genetic information carried by the DNA is transcribed into RNA. This transfer of information is based on the same principle as the duplication of DNA, i.e. the pairing of complementary bases (we will see [...]
Everything you need to know about ribosomal RNA in microbial technology. Some of the questions are as follows:- Q.1. What is rRNA? Ans. The rRNA is ribosomal RNA of various sizes and forms the part of ribosomes. It comprises 90% of total RNA of the cell while the remainder part of the ribosomes comprises ribosomal proteins. Q.2. Give types of [...]
In this article we will discuss about the meaning of tRNA. The genetic message contained in the nucleotide sequence of transcribed RNA cannot be read off directly by the amino acids in the polypeptide chain. Crick and Hoagland were first to postulate that an intermediate RNA molecule functions as an "adaptor" into which the amino acid is plugged so that [...]
