In Eukaryotes, there are 3 RNA Polymerases.
RNA Polymerase I → rRNA.
RNA Polymerase II → mRNA.
RNA Polymerase III → tRNA.
Alphabetically r, s (m), t.
Eukaryotes have Split genes.
Processing of RNA occurs in 3 steps:
1. Splicing: removal of introns and joining of exons.
EXons EXpressed, INtrons IN the trash.
2. Capping: addition of methylguanosine phosphate caps at 5′ end.
3. Tailing: poly-adenylation occurs at 3′ end.
Alphabetically and Numerically
3 & A comes first, so A at 3′ end.
5 & G comes later so G at 5′end.
