This question asks, mature m rna from a uchariot would contain each of these features except which of the following.
00:09
So we have exxon encoded rna, intron encoded rna, a 5 prime cap, and a 3 prime polyate tail.
00:18
So we know that mrna contains, specifically eukaryotic mra, contains a 5 prime cap and a 3 prime polyate tail.
00:25
So we know that choices c &d are not going to be our answers.
00:28
And we know that they have this because there is a lot of mrna processing that occurs in eukaryotes.
00:39
And prokaryotes don't have this.
00:42
So the 5 prime cap, 3 prime polyate tail, will be found in our eukaryotic mature mrna.
00:49
Now we just have to differentiate between exon encoded rna and intron encoded rna.
00:53
So we know that exons are expressed.
00:57
So these are going to be our coding regions of mri.
01:01
And then we also have introns.
01:03
And introns are going to be what is usually referred to as junk dna...
