00:01
We have the coding sequence of the dna.
00:03
It's tga.
00:04
We want to know the anticozon on the trna that will bind to the codon.
00:09
So there are two strands of dna.
00:11
Here they are.
00:13
One of them is tga, and this is the coding strand.
00:21
So here is the coding strands.
00:23
The other strand is called the template strands.
00:27
So it's important to remember these two strands because the mrna is only going to be based on one of these.
00:33
And the mrna is based on the template, not the coding.
00:38
So the mrna is transcribed from the template strand.
00:45
So we know the base pairing rules.
00:47
We know that cytosine goes to guanine and vice versa.
00:51
We know the adenine goes to thymine on dna and uracil on rna.
00:57
So if the coding strand is tga, the template strand will be complementary.
01:04
So thymine goes to adenine, guanine goes to cytosine, adenine goes to thymine.
01:10
So this is the template.
01:12
Now let's separate them and see what happens.
01:17
So the mrna is based on the template strand.
01:22
So the mrna comes in here and it is complementary to the template...
