Question 53

(Short Answer)

Indicate true (T) and false (F) statements below regarding the accuracy of translation by the ribosome. Your answer would be a four-letter string composed of letters T and F only, e.g. TFFF.
( ) The difference in the binding affinity of a codon to a correct versus incorrect anticodon CANNOT by itself account for the high accuracy of translation.
( ) GTP hydrolysis by EF-Tu both speeds up translation and increases its accuracy.
( ) The ribosome can detect correct Watson-Crick base-pairing between the codon and anticodon in the A site, and consequently trigger GTP hydrolysis by EF-Tu.
( ) Even after GTP hydrolysis by EF-Tu, the ribosome can prevent wrong amino acid incorporation by kinetic proofreading.

The difference in affinity between cor...
