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 ...

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 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 ...
