1. Answer TRUE or FALSE for the following statements:
a) tRNAs are translated into proteins.
b) Perfect fit amino acids do not bind at the editing site.
2. tRNA synthases selectively bind_________
a) tRNA. b) amino acids. c) both A and B
3. Ribosomal RNAs are produced _______
a) in the nucleus b) in the nucleolus c) both A and B
Homework Answers
1. a) tRNAs are translated into proteins - False
b) Perfect fit amino acids do not bind at the editing site - True
2. tRNA synthases selectively bind amino acids.
a) tRNA. b) amino acids. c) both A and B
Explanation: A tRNA molecule has clover shaped structure whose sequence is held by hydrogen bonds. One end of the tRNA binds to amino acid and the other end has anticodon that binds to mRNA codon.
3. Ribosomal RNAs are produced in the nucleolus.
a) in the nucleus b) in the nucleolus c) both A and B
Explanation: mRNA is translated to Ribosomal proteins in the cytoplasmic region by ribosomes in nucleolus.

6. All of the following statements about tRNAs are true EXCEPT: O A tRNA may use non-conventional base-pairing to bind to the codon. O A TRNA cannot fully enter the ribosome until it is released by the elongation factor. O A tRNA brings the correct amino acid for the corresponding codon in the mRNA during translation. O A tRNA catalyzes the formation of the peptide bond between amino acids.
