In order to answer this question, let's talk about not genetic code.
00:04
It says if a protein coding gene undergoes a mutation where g -a -g is changed to g -a -g.
00:15
So, if you look at the genetic code table that you can find on internet, okay? according to that, g -a -g codes for glutamate.
00:31
Okay? so this is the original amino acid.
00:34
But because of this mutation, you're changing g -a -g by uag.
00:39
It means you're changing this g by an eu.
00:43
And you're producing uag.
00:45
And according to the genetic code table, uag goes for a stop codon.
00:51
So it says, what kind of mutation is it? and this is an example of a nonsense mutation.
01:02
And what is a nonsense mutation? well, a nonsense mutation is when you have, a mutation, for example in this case, you changed your g by a u, and the resulting amino acid is a stockcote where a normal amino acid should be.
01:17
So you're producing practically a premature stock column...
