There are 61m rna codons that specify an amino acid, but only 45 trnas.
00:07
Is this explained by the fact that, a, some antichodons recognize two or more different codons.
00:14
The rules for base pairing between the third base of the codon and the trna are flexible.
00:19
Many codons are never used, a and b, or all of them.
00:23
So i'll start by ruling out c and by extension e.
00:26
All of the codons are used.
00:28
There are 64 codons, three of the stop codons.
00:31
61 of amino acids, they are all used.
00:36
So it's not better.
00:38
So what is it? let's look at the interaction.
00:41
So we have an m rna and it has a codon on it.
00:45
We also have the t -r -na.
00:48
It has this clover shape.
00:49
It's single -stranded but it loops in on itself and binds to itself...
