Hello everyone! In this video we will talk about the RNA. RNA stands for ribonoclake acid. And like DNA, RNA is a single strand poorly nucleotide chain. The nucleotide presents an RNA have O-Ach on carbone number 2 in the pentose sugar. And have uracil instead of thiamine in that nitrogenous paste. In eukaryotic cell, 50% of RNAs present in ribosomes and drop into plasma retaculum, 25% of RNA is present inside of latham, 15% of RNA is present in mitochondria, and 10% of RNA is present in nucleus and nucleus loss. Types of RNA. RNA can be of various different types. RNA initially divide itself into coding and non-coding RNA. The coding RNA consists of messenger RNA. The non-coding RNA further divides itself into housekeeping non-coding RNA, regulatory non-coding RNA. Non-coding RNA contains transfer RNA and ribosomal RNA. Regulatory non-coding RNA further classified itself into long-long-coding RNA and small non-coding RNA. Long-long-coding RNA have more than 200 nucleotides. And small non-coding RNA have less than 200 nucleotides. Small non-coding RNA is further classified into five different types that are microRNA, as an O-RNA that stands for small nuclear RNA. As I-RNA that stands for small interfering RNA, as an RNA that stands for small nuclear RNA, PI RNA that stands for BV interacting RNA. Thanks for watching this video.
