Okay, so with this worksheet, we're going to go ahead and fill in the chart below.
00:07
It seems like you have a pretty good handle on the use of this chart, the codon chart, going from dna to mrna, and then from mrna to protein.
00:23
Oh, i guess what you might be confused on is a trna anti -codone, so let's go ahead and fill this out so you have an idea.
00:29
Let's go ahead and take this one.
00:32
Ggc, that's the dna triplet.
00:34
So the mrna codon is going to be, of course, c, c, g, because it's complementary to the dna triplet.
00:41
Then we move on to the trna anticoanon, which is going to be a complementary sequence to the mrna codon, which, what did you know it, is actually going to be somewhat similar to the tna triplet.
00:53
So it's going to be ggc.
00:56
I say somewhat similar, because in cases in which t is used, in the dna codon, in the dna triplet, sorry.
01:05
In the t rna codon, of course, rna doesn't use t's.
01:08
They use u, so instead of a t, it'll be a u.
01:12
Nonetheless, our tna anticonans can be ggc, right? for the amino acid, of course, we can basically go off of the mrna codon, which is ccg, so then the amino acid here is going to be c -c -g -proline, pro.
01:42
Now, they're asking for the t -r -a anticodon, but that is actually not what is not what the chart.
01:49
This codon chart is using, the codon chart is using mrna.
01:54
Right, so this is in response to the mrna.
02:00
The t -r -n -a is simply a complementary sequence to the mrn -n -n -a.
02:06
Which brings in the amino acid.
02:11
So again, here's the trna.
02:13
This brings in the amino acid, which is attached to this end here.
02:21
So this section here, this section here is the anticoadone.
02:31
Typically, the amino acid is on this other end.
02:36
Okay, so going ahead and filling in the rest of the chart, i'll just use some movie magic, and i've gone and completed.
02:45
This chart and so this is essentially what we're looking at and actually let's go ahead and use something as an example here let's do this one here c -a -g as an example if you have c -a -g as an m -r -n -a codon we want to find the complementary of that so that's going to be g of course complementary of a is t and we're in dna so that makes sense and then c for g okay so that's how we do that...
