You know, let's answer this question.
00:04
Let's talk about post -transcriptional modifications.
00:07
Okay, it says, which is the following occurs in prokaryotes, but not in you carots? you remember that if this is your dna, there is a process called transcription by which you transcribe a gene in dna and convert a messenger rna.
00:27
In your cariotic cells, this process occurs in the nucleus, okay? and then your messenger rna has to leave the nucleus and go to the ribosomes where it is going to develop the process of translation.
00:43
But this messenger rna before leaving the nucleus, it has to develop some post -transcriptional modifications that are, for example, the removal of intros and splicing infections, also the 5n capping and the polyaddening tails.
01:01
Okay? so those are three post -transcriptions.
01:04
And modifications that have procured here in order for your messenger rna to become a mature messenger rna.
01:09
This is in contrast to prokaryotic cells...
