Question

A-The region of the tRNA that is complementary to the triplet onthe mRNA is
1. The acceptor stem
2. The codon
3. The peptidyl site
4. The anticodon
5. The adaptor loop

B-During translation, the ribosome must move along the mRNA.This movement
1. requires the ribosome to come apart intosubunits
2. requires an accessory factor andenergy
3. does not require energy, but requiresthe ribosome to change conformation
4. requires accessory factors and usesenergy from peptide bond formation

C-A nonsense mutation
1. results in large scale change to achromosome
2. will lead to the premature terminationof transcription.
3. will lead to the premature terminationof translation
4. is the same as atransversion
