rRNA (ribosomal RNA) is important because it makes up a key part of the ribosome, the cellular complex responsible for protein synthesis. It helps in decoding mRNA to produce the corresponding amino acid sequences needed to build proteins. Without rRNA, the process of translation and protein synthesis would not occur efficiently in cells.
mRNA, rRNA, and tRNA
There are different types of ribosomal RNA (rRNA) in the body, with 80-90% of cellular RNA being rRNA. Each ribosome contains 4 different rRNA molecules: 28S, 18S, 5.8S, and 5S rRNA. These molecules combine to form the structure of the ribosome, which is essential for protein synthesis.
rRNA is transcribed from genes located in the nucleolus of the cell. It is transcribed by RNA polymerase I.
The 16s rRNA genes (rDNA) exist on genomic DNA. Therefore, plasmid has nothing to do with its amplification. However, if the 16s rRNA gene is cloned into the plasmid, it can be amplified.
The primary function of rRNA is in protein synthesis – in binding to messenger RNA and transfer RNA to ensure that the codon sequence of the mRNA is translated accurately into amino acid sequence in proteins. The function of rRNA is to serve as a location for protein synthesis. rRNA is the location in which mRNA and tRNA are able to come together to synthesize proteins.
Ribosomal ribonucleic acid, also known as rRNA, is important for making proteins because these proteins help to link evolutionary relationships of a species. Each rRNA consists of 40% of protein.

Ribosomal RNA (rRNA) is the most abundant type of RNA in cells. It is a key component of ribosomes, the cellular machinery responsible for protein synthesis.

RIBOSOMES!
A ribosome is composed of two subunits, a large subunit and a small subunit, made up of a combination of ribosomal RNA (rRNA) and protein molecules. The large subunit is responsible for peptide bond formation during protein synthesis, while the small subunit helps in mRNA recognition and initiation of protein synthesis.
Ribosomal RNA (rRNA) is the type of RNA that is the major component of cellular ribosomes. Ribosomes are composed of both rRNA and proteins, with rRNA providing the structural and catalytic framework for protein synthesis.
