All right, welcome, and thanks for joining me today in a video about human complexity and our genome.
00:06
So this is a multiple choice question, which is asking, how can us humans have so much complexity with actually not that much coding content? in other words, not that many genes.
00:17
We only have 20 ,000 or so coding genes.
00:21
It's actually a lot less in many other organisms, but yet how can we be so complex? so there's two reasons for that that i'll go through.
00:27
The first one is alternate splicing.
00:30
So this has to do with dna and rna editing.
00:33
So imagine if we have a gene here.
00:35
I'm just going to draw black line to show a gene.
00:37
And genes are made of introns and exons.
00:40
Introns are cut out.
00:41
They are non -coding regions.
00:43
And the exons are spliced together.
00:45
That will leave these different exons.
00:47
So let's say we have exxon 1, 2, 3, and 4.
00:51
And this would actually be rna after transcription...
