Okay, so we have this process called gene expression.
00:14
And that can be thought of in exactly the same way we use this term expression in our daily lives.
00:21
You're taking the sort of information within a gene and you're turning it into a functional molecule like a protein.
00:30
And there's this sort of trickiness in here.
00:35
So we have this molecule called dna, and that dna, its main job is to serve as a store of information, these genes that go on to make up an organism.
00:51
And one of the difficulties here is that dna can be sort of thought of as sort of boxed up and packaged up in a way that's not super accessible on its own.
01:04
You have these two strands, these backbones that run down the side that then between them store these base pairs in the form with that kind of get snapped together via hydrogen bonding.
01:23
So you have this information inside the dna molecule, but naturally it's a little bit tough to access.
01:33
So usually what happens is that you have to figure out some way to sort of unzip this molecule and expose this information inside.
01:45
And what typically happens through that process is that you make an rna copy of the dna molecule.
01:56
And that rna is sort of going to be like a dna molecule with a few differences here and there...
