Our original dna strand, t -a -c -g -c -a.
00:04
We are going to then find our complementary strand.
00:08
A couple things to keep in mind here is a pairs with t and c pairs with g.
00:15
So our complementary strand to our original would be a pairing with t, c pairs with g, and there is our resulting complementary strand.
00:27
Now during dna replication, our double -stranded molecules so both of those strands would split apart and each would be essentially duplicated in using those strands as the template.
00:41
So very similar to the original process, a pairing with t, c pairing with g, we then end up with two strands, two complete double -sided strands from the original that we started with.
00:59
When we're talking about specifically transcription here, we take one of those strands and we code it and use that as a template strand to encode for mrna.
01:11
Very similar process in terms of matching up base pairs, but one main difference here in mrna is that a, instead of having the base of thymine, mrna has the base of uricil.
01:30
So anywhere where there would have been a t and our original sequence we now end up with a u.
01:37
And so our resulting mrna sequence from our original template strand is augg cgu.
01:46
And the way that we then go from transcription to translation and actually get proteins being made is the t rna which is paired with an amino acid matches up with that mrna and brings those amino acids to the ribosomes where they can then be combined together into proteins.
02:10
So using our codon chart over here to find the appropriate amino acid, the first thing we're going to do here is match up our t rna.
02:23
So again, very similar process...
