canonical base pairing def

A

A=T C=- G A=U

18
Q

Wobble Base Pair

A

I with either A/C/U

19
Q

what is a 2 degree. or secondary structure

A

it went through foldingq

20
Q

Aminoacyl tRNA synthetases def

A

plays a critical role in translation : charging tRNAs with the correct amino acid

21
Q

active sites of a synthetase are what

A

tRNA based on its anticodon
amino acid

22
Q

what is the purpose for wobble base pairing

A

to reduce the number of unique tRNAs and aminoacyl tRNA synthetases

23

A

on the 3’ most nucleotide fo the codon
