____11. Enzymes called amino
acyl- tRNA synthetases:
a.
Synthesize tRNA
b.
Attaches amino acids to tRNA
c.
Strips tRNA from its amino acid in the process of
translation
d.
Destroys excess tRNA
e.
Helps tRNA synthesize amino acids
____12. In the process of
translation:
a.
A strand of mRNA is fromed with the nucleotide sequences
complementary to those of DNA
b.
Nucleotide sequences of tRNA are established
c.
A polupeptide is formed in response to the rRNA nucleotide
sequence
d.
rRNA is synthesized with seuqences ccomplementary to those of
tRNA
e.
A polypeptide is formed as dictated by the nucleotide sequence
in mRNA
____13. As polypeptides are
formed at the ribosome, elongation continues until:

f-Met attaches to the start codon
b.
A release factor attaches to the stop codon
c.
A large ribosomal unit binds to the small ribosomal unit
d.
tRNAs exit at the E site of the ribosome
e.
A peptide bond is catalyzed by peptidyl transferase
