Ribonuclease
Helicase
DNA polymerase
What are the three main stages of translation?
Initiation, Elongation, Termination
Selection, Integration, Resolution
Preparation, Execution, Conclusion
Activation, Stabilization, Deactivation
Where does translation occur in the cell?

Golgi apparatus
Cytoplasm
What is the role of ribosomes in protein synthesis?
Ribosomes transport amino acids to the nucleus.
Ribosomes store genetic information for protein synthesis.
Ribosomes synthesize proteins by translating mRNA into amino acid sequences.
Ribosomes break down proteins into smaller peptides.
Define codons and their significance in translation.
Codons are essential for translating genetic information into proteins, determining the sequence of amino acids in a protein.
Codons are responsible for DNA replication.
Codons are the building blocks of carbohydrates.
Codons are used to store genetic information in the nucleus.
How do anticodons relate to codons during protein synthesis?
Anticodons are complementary to codons and ensure the correct amino acid is added during protein synthesis.
Anticodons are unrelated to codons and function independently during protein synthesis.
Anticodons are identical to codons and do not affect amino acid addition.
Anticodons are found in DNA and do not play a role in protein synthesis.
What is the start codon and why is it important?
AUG is the stop codon, which terminates translation.
AUG is a type of amino acid that is not involved in protein synthesis.
AUG is the only codon used for all proteins.
AUG is the start codon, and it is important because it initiates translation and sets the reading frame for protein synthesis.
Explain the difference between mRNA, tRNA, and rRNA.
tRNA is responsible for DNA synthesis.
mRNA is involved in DNA replication.
mRNA carries genetic information, tRNA transfers amino acids, and rRNA forms ribosomes.
rRNA transports genetic material.
What happens during the elongation phase of translation?
tRNA molecules are released from the ribosome.
The polypeptide chain is cleaved into individual amino acids.
Ribosomes disassemble the mRNA strand.
Amino acids are sequentially added to the growing polypeptide chain.
