CELLULAR RNA Meaning and
Definition
-
Cellular RNA refers to the various types of ribonucleic acid molecules that exist within the cells of an organism. RNA, or ribonucleic acid, is a nucleic acid polymer composed of nucleotide building blocks. These nucleotides are linked together by phosphodiester bonds to form a single-stranded chain.
In cells, RNA is involved in a multitude of essential biological processes, including gene expression, regulation, and protein synthesis. The term "cellular RNA" encompasses different types of RNA molecules, each serving specific functions.
One important type of cellular RNA is messenger RNA (mRNA). mRNA is transcribed from DNA and carries the genetic information from the nucleus to the ribosomes in the cytoplasm, where it is translated into proteins. Another form of cellular RNA is transfer RNA (tRNA), responsible for delivering the correct amino acids to the ribosomes during protein synthesis. Additionally, there is ribosomal RNA (rRNA), a crucial component of ribosomes that aids in the assembly of proteins.
Apart from these three major types, cells also contain other forms of RNA, such as small interfering RNA (siRNA), microRNA (miRNA), and long non-coding RNA (lncRNA). These non-coding RNAs play critical roles in gene regulation, post-transcriptional modifications, and other cellular functions.
Overall, the term "cellular RNA" encompasses the diverse population of RNA molecules found within cells, each fulfilling specific roles in various biological processes necessary for cellular functioning and organismal development.

Etymology of CELLULAR RNA
The word "cellular RNA" consists of two main components: "cellular" and "RNA".
1. "Cellular" refers to "cell", which originated from the Latin word "cellula", meaning "a small room" or "a little cell". was introduced by the English scientist Robert Hooke in the 17th century when he first observed and described the structure of cork cells under a microscope. "Cellular" implies anything related to or pertaining to cells.
2. "RNA" stands for "ribonucleic acid". The term "nucleic acid" was coined by the Swiss biochemist Richard Altmann in 1889. He used this term to describe the chemical composition of the nucleus of living cells. The word "ribonucleic" is derived from two components:
- "Ribose" refers to the sugar molecule Ribose that is a key component of RNA.
