INFORMATIONAL RNA Meaning and
Definition
-
Informational RNA, also known as messenger RNA (mRNA), is a type of RNA molecule that plays a crucial role in the flow of genetic information in living cells. It acts as an intermediate carrier of genetic instructions from the DNA to the ribosomes, where they are translated into proteins during the process of protein synthesis.
The process of converting genetic information encoded in DNA into functional proteins is a fundamental biological process that occurs in all living organisms. Messenger RNA serves as a blueprint or template for this translation process. After being transcribed from the DNA template by an enzyme called RNA polymerase, mRNA carries the genetic code outside the nucleus of the cell and interacts with the ribosomes in the cytoplasm or endoplasmic reticulum.
The mRNA molecule consists of a sequence of nucleotides, namely adenine (A), cytosine (C), guanine (G), and uracil (U), which differs from the thymine (T) present in DNA. This sequence of nucleotides is called a codon and represents specific amino acids that are to be joined together during protein synthesis. The ribosomes, reading these codons on the mRNA, direct the actions of transfer RNA (tRNA) molecules, which carry the corresponding amino acids to the ribosome, allowing for protein synthesis.
Overall, informational RNA is a vital component in the transmission of genetic information from the DNA to the protein-making machinery within a cell, playing a pivotal role in the regulation of cellular functions and the overall life processes of organisms.

Etymology of INFORMATIONAL RNA
The term "Informational RNA" refers to a specific type of RNA molecule that carries genetic information. However, it is not a commonly used or widely recognized term in biology.
If you are referring to "mRNA" (messenger RNA), which is the most well-known type of informational RNA, its etymology can be broken down as follows:
1. Messenger: The term "messenger" describes the role of mRNA in biology. It conveys the genetic information from DNA to the ribosomes, where protein synthesis occurs. The term "messenger RNA" was coined by Jacob and Monod in 1961.
2. RNA: RNA stands for ribonucleic acid. It is a molecule similar in structure to DNA but with a single strand. RNA plays various roles in the cell, including carrying genetic information, catalyzing chemical reactions, and regulating gene expression.
