Hi, welcome.
00:01
And thanks for joining me today in a video about how can a single gene make many different proteins.
00:08
So it's kind of a number of genes versus number of proteins question.
00:12
This all has to do with rna processing and alternative splicing.
00:19
So if we think about dna, dna codes for rna, specifically usually messenger rna, and that in fact is translated into a protein.
00:28
So i have a very simple diet.
00:30
Of a gene shown below here in black and red.
00:34
So, and i have some things numbered, i'll go through as well.
00:37
So imagine that line, that line going from left to right there is a gene.
00:41
Well, a gene, dna is made up of a couple of different parts.
00:45
What i have numbered in black to the top, numbered in black are what are called exons...
