Prokaryotic organisms contain one type of rRNA gene that encodes three distinct RNA species: the 23S, 5S, and 16S rRNAs. In comparison, eukaryotic cells contain two types of rRNA genes that give ...

The remaining mass consists of a number of proteins — nearly 60 in prokaryotic cells and over 80 in eukaryotic cells. Within the ribosome, the rRNA molecules direct the catalytic steps of ...

The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit contains the 16S rRNA, while in eukaryotes, it contains the 18S rRNA. These rRNAs are involved in mRNA binding and ...
