Question
A-The region of the tRNA that is complementary to the triplet on the 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 into subunits
2. requires an accessory factor and energy
3. does not require energy, but requires the ribosome to change conformation
4. requires accessory factors and uses energy from peptide bond formation
C-A nonsense mutation
1. results in large scale change to a chromosome
2. will lead to the premature termination of transcription.
3. will lead to the premature termination of translation
4. is the same as a transversion

Explanation / Answer
Hi!
A-The region of the tRNA that is complementary to the triplet on the mRNA is
1. The acceptor stem
2. The codon
3. The peptidyl site
4. The anticodon This is the part of the tRNA which "matches" the mRNA
5. The adaptor loop
B-During translation, the ribosome must move along the mRNA. This movement
1. requires the ribosome to come apart into subunits
2. requires an accessory factor and energy (Protein elongation factor and GTP/GDP)
3. does not require energy, but requires the ribosome to change conformation
4. requires accessory factors and uses energy from peptide bond formation
C-A nonsense mutation
1. results in large scale change to a chromosome
2. will lead to the premature termination of transcription.
3. will lead to the premature termination of translation (Causes nonfunctioning protein product)
4. is the same as a transversion
