1.Â Â Â Â Â tRNA aminoacylation
a.Â Â Â Â Â What is aminoacylation? Whereon the tRNA does it occur?
b.Â Â Â Â Â Why is ATP required foraminoacylation? Why is the hydrolysis of PPi generated duringaminoacylation important?
c.Â Â Â Â Â Â What is the significanceof the high-transfer potential of the ester bond created duringtRNA aminoacylation?
d.Â Â Â Â Â Why is the specificity ofaminoacyl-tRNA synthetases important? How do these enzymes ensuretheir specificity?
e.Â Â Â Â Â Are you familiar enough withamino acid side chains to answer questions about aminoacyl-tRNAsynthetase specificity? (e.g. how might similar amino acids likevaline, serine and threonine be distinguished?)
f.Â Â Â Â Â Â Â Do you understandwhy there are differences in amino acid recognition betweenactivation and editing sites? And how those differences dictate thespecificity of the two different activities?
