For this question, we have three different molecules.
00:03
We have a pre -mrna strand.
00:05
We have an mrna strand.
00:07
And we have a mutated version of the mrna strand, meaning it has a difference in the gene structuring between the regular rna strand and the mutant form.
00:19
So when we look at this question and the answers, we are looking for exons and introns inside of this mrna sequence.
00:29
So exons are the parts or the genes that are going to be expressed when we make the protein, whereas the introns are going to basically be the fillers or random sequences in between that aren't going to be used inside of the protein.
00:47
You can imagine these to be like ads inside of a magazine, for instance.
00:52
So if we consider our exons and introns in these molecules, our pre -m rna is going to include, both those exons and the introns.
01:04
However, the pre -m rna strand is going to undergo processing inside of the nucleus of the cell to be converted into the finalized mrna strand.
01:18
And that's going to include the process of alternative splicing and the removal of those introns.
01:27
So here, the mrna strand is going to be exxons only...
