You're not to answer this question.
00:01
Let's talk about dna.
00:04
It says draw that dinuclotide, that is this one, this one here.
00:12
Okay? so in this case, they're asking you to draw this.
00:17
First, they are on the same strand because guanin does not pair with timing.
00:23
Guaning always pairs with cytosine, while timing always pairs with aden.
00:28
So in this case, over a dinuclite would be like this.
00:32
Let's first draw, the thyme in here, okay? so you have here, let's suppose this is your pentose sugar because each nucleotide is made of a pentose sugar and here you have the thymeans.
00:51
Now this is your nitrogenose base, this is your pentose sugar that has five carbons, specifically this is carbon number one, this is carbon number two, this carbon number three, carbon number four and carbon number five.
01:10
So here you have oh and h.
01:17
This is the nucleosite, but you have here also a phosphate.
01:26
So practically at the 5 carbon, the phosphate is going to be attached here.
01:31
Now this is the thymine.
01:36
Now you have the warning.
01:37
So the 1 is going to be here.
01:54
1 in the h and here is the 5 carbon number.
02:08
And this is what you have.
02:10
Okay.
02:10
So this is your dinuclidate.
02:14
And why is this the 3nd and why is this a 5 end? well, because of this.
02:18
You have that the carbon number 3 is at this side.
02:21
So this is a 3 end.
02:22
And the carbon or this nucleotide here ends at the 5 carbon.
02:27
So this is the 5 end...
