Codon Recognition By tRNA Flashcards
1
Q
Describe antiparallel binding between codon and anti codon
A
- binding follows rules of complimentary base pairs
- 5’-3’ codon read and paired by 3’-5’ anticodon
2
Q
Describe wobble hypothesis and application
A
- 1st 2 nucleotides on anticodon follow Watson-crick rules
- last nucleotides of anti codon not spatially defined / less stringent
-allow a tRNA to recognize more than 1 codon
3
Q
List the purines and pyrimidines
A
1 Adenine / guanine
2 cytosine/ uracil / thymine
4
Q
List the wobble base pairs
A
1st is tRNA and 2nd mRNA
A - U C - G G - C / U U - A / G H - U / C / A
5
Q
Describe hypoxanthine
A
-product of adenine deamination and base in e nucleotide inosine monophosphate
