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

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
