Now, RNA polymerase has become a full-fledged pre-mRNA!!
Pre-mRNA suddenly feels 7 guanine on his 5' end and 50-250 adenine on his 3' end...
Before pre-mRNA sets out on his journey, the king grants him with the blessings of poly-A-tail and 5' cap.
Pre-mRNA seeks out the spliceosome witch, who peers into pre-mRNA's soul and finds introns (non-coding regions) among his valuable exons (coding regions).
The spliceosome witch removes the evil introns.
With all the holy blessings he received, pre-mRNA has now ascended and become mRNA.
mRNA is now ready to traverse the cytoplasm forest and seek the dark knight tRNA's castle (ribosome).
mRNA doesn't realize that tRNA was waiting for his arrival and has a plan to use mRNA to his advantage...
tRNA's plan commences with initiation.
mRNA is attacked by tRNA and his ribosome subunits!!!
They're trying to find his start codon (AUG) and read his genetic code!
