Translation Quiz Answers
What happens after the polypeptide chain leaves the ribosome?
- It is folded into a protein.
- It is reused to produce more polypeptide chains.
- It enters the cytoplasm and catalyses specific reactions.
- It breaks up into amino acids and carries out functions within your cells.
- The mRNA transcript runs out.
- The amino acid supply gets depleated, and as a result, translation is halted.
- The stop codon is encountered.
- The ribosome does not, it has a life span. It can only translate for so long before the large and small subunits fall apart.
- A site, T site, E site
- A site, P site, E site
- A site, P site, F site
- I site, P site, E site
- A codon is set of three nucleotides that code for an amino acid.
- A codon is a set of any number of nucleotides that code for an amino acid.
- A set of nucleotides found on the arm of a tRNA.
- None of the above.
- It breaks apart the large and small subunit of the ribosome.
- It frees the mRNA from the ribosome.
- It removes the polypeptide chain from the ribosome.
- It removes the polypeptide chain and the mRNA from the ribosome.
- It helps the tRNA enter the various sites the the ribosome.
- It binds the small subunit to the large subunit.
- It folds the polypeptide chain into a protein after leaving the ribosome.
- It binds together the two amino acids introduced by the tRNA.
- Initiation, Elongation, Termination
- Initiation, Termination, Final Modifications
- Initiation, Production, Final Modifications
- Elongation, Termination, Final Modifications
- To destroy old proteins based on the instructions provided by the mRNA.
- To read mRNA and build polypeptide chains which fold into proteins.
- To read mRNA and carry out functions within the cell.
- To read the proteins and produce the correct mRNA transcript.
- Initiator tRNA enters P site and the next tRNA enters A site and their amino acids bind together. As the ribosome moves along the mRNA, the initiator tRNA is moved to the E site while the other tRNA is moved to the P site.
- Initiator tRNA enters A site and as the ribosome moves along the mRNA, the initiator tRNA is moved to the P site while the next tRNA enters the A site. Their amino acids are bonded together during the process.
- It does not matter, it can be read in either direction.
- 3' to 5'
- 5' to 3'
- 3' to 3'
