Answer Key
1. What occurs first, transcription or translation? Transcription.
2. The main goal of translation is to turn mRna into peptide chain
3. Translation occurs on the ribosome which are found in the cytoplasm or the
endoplasmic recticulum.
4. Translation consists of three parts: initiation, elongation, and termination.
5. Codons are triplets found in mRNA while anticodons are triplets found in
tRNA.
6. Do codons overlap? No

7. Explain why shifting the reading frame during a mutation is very dangerous.
It can change the amino acids translated/length of the peptide chain.
8. The initiator tRNA contains what amino acid? met This corresponds to what
base pairs on the start codon? AUG
9. The three sites in the ribosome for tRNA are the aminoacyl site (A),
peptidyl site (P) and exit site (E).
10. New tRNA (after the initial met tRNA) comes in at the A site, then moves
to the P site as it gets the polypeptide added to it. Then, after becoming
uncharged it moves the E site and is later recycled
11. When the stop codon is reached, what binds instead of the tRNA? Release
factors
12. Name two enzymes important in translation and what they do.
Aminoacyl tRNA synthase adds amino acids to uncharged tRNA.
Peptidyl transferase adds new amino acids to peptide strand.
