Okay, so we have a dna strand and we want to know what the amino acid sequence is.
00:05
So i have it set up for us here with our code on chart.
00:08
We have the dna strand.
00:10
And before we can look at this code on chart, we have to turn it into mrna.
00:14
And the way to do that is just to match the letters.
00:20
So t goes with a, but in mrna and any rna, there's no t's.
00:25
So instead of putting a t here to go with a, we put a u.
00:28
C and g stay the same.
00:30
So then we have g, g, g, g.
00:31
And then a goes with t, g goes with c, c goes with g, and then we have another c.
00:39
Remember, we want to put a t here, but there aren't any t, so we put a u, another c, and then a u, you'll see that i have them kind of separated into threes because codons are three base pairs.
00:54
And so now i can read my chart...
