rRNA NOTES

rRNA ;
       Ribosomal RNA constites the larger part of total cellular RNA.
It is synthesis in a nucleus.

Types :-

 Eukaryotes - 28S rRNA , 80S rRNA , 5.8S rRNA , 5rRNA
28S, 5.8S and 5S rRNA occur in 60S Ribosomal subunits.
80S rRNA occurs in 40S ribosomal subunit.

Prokaryotes - 23S rRNA , 16S rRNA , 5S rRNA
23S rRNA , 5S rRNA occurs in 50S ribosomal subunit.
16S rRNA occurs in 70S ribosomal subunit.

Functions of rRNA ;
The rRNA formed extend in 2° structure and place an active role in conserved of mRNA , TRNA.
In Eukaryotes 50 to 5000 sets of rRNA genes and as many as million ribosomes maybe present in a single cell.
In prokaryotes have fewer sets of rRNA genes and ribosomes cell.
Make a protein ribosomes like together amino acid.
Liking amino acid together function of rRNA in the larger subunit of ribosomes.
