Hi, to answer this question, let's talk a little bit about protein synthesis.
00:07
In other words, how proteins are made from dna.
00:12
So the first thing that happens is the dna, the code, is read and made into messenger rna.
00:21
This is referred to as transcription.
00:31
So transcription makes the messenger rna.
00:42
Messenger rna is a single strand that contains the code three letters at a time.
00:52
So perhaps we have uac, g, g, g, a, t.
01:10
Whoops, back that up.
01:11
There is no t in messenger rna.
01:14
I'm just kind of making something up here.
01:17
So, and then acc, and then we'll dot, dot, dot.
01:20
So this is my messenger rna.
01:26
The messenger rna is made up of three letter codes known as codons, and each codon represents an amino acid.
01:43
So this now needs to be translated...
