In this article we will discuss about the processing of rRNA in prokaryotes (e.g. E. coli) and eukaryotes (e.g. mammals). In prokaryotes (e.g. E. coli) there are seven operons for rRNA. These are dispersed throughout the genome. Each operon consists of one copy of each of the 5S, 16S and 23S rRNA sequences. Coding sequences […]

Types of RNA (Ribonucleic Acid): 4 Types
Article Shared by 
The following points highlight the four types of RNA. The types are: 1. Ribosomal RNA 2. Transfer RNA 3. Messenger RNA 4. Genetic RNA. Type # 1. Ribosomal RNA (rRNA): It is the most abundant RNA (70-80% of total) which has 3-4 types. Some of its types (23S, 28S) are the longest of all RNAs. […]
Maturation of mRNA from HnRNA | Plant Physiology

In this article we will discuss about the maturation of mRNA from HnRNA. In higher organisms, within the nucleus, heterogenous nuclear RNA (HnRNA) or high molecular weight RNA (HMW RNA) or DNA-like-RNA (dRNA) is synthesized. These molecules are larger than mRNA and used in cytoplasm. Polymerase-I is added at 3′-end of HnRNA. Subsequently mRNA molecule […]
