This question is asking about transcription and translation.
00:05
So i've copied over the template strand from your textbook because that is the strand that will be used as a template for transcription mrna synthesis.
00:18
And remember that when the mrna is being transcribed off of this template strand, it will follow the base pairing rules.
00:26
So we know that a always pairs with t and g, always pairs with c, but for mrna, there are no thymine residues, so we have to use uracil instead.
00:42
So a will actually bind to u.
00:45
So just based off of those base pairing rules, we can just go down a line and a c will bind to a g.
00:52
So i'll add to a g, g, g, t will bind to an a.
00:58
So g, g, g, a, c will bind a g, g, g, a, c, u, a, c, u, a, c, g, and then u, u, you'll notice that this mrna sequence is basically identical to the non -template strand, except that all of the t's have been replaced with u's.
01:37
So this is our mrna sequence, which i've just written out for you here...
