1) One class of aminoacyl tRNA synthetases possesses "proofreading" abilities. An experiment was carried out where a cysteine attached to tRNA was chemically modified to an alanine.
a) Could this modified charged tRNA be able to be placed the alanine into the primary sequence of a protein?
b) Would IF-2 recognize this modified aminoacyl tRNA?
c) Would EF-Ts recognize this modified aminoacyl tRNA?
