10 Questions
What happens when a stop codon is encountered during translation?
A release factor binds with the ribosome.
What aids in the proper folding of complex polypeptides as they exit the ribosome?
Chaperones
Which feature of tRNAs pairs with the codon in the mRNA during translation?
Anticodon loop
What is a characteristic of prokaryotic mRNA molecules?
They lack a scanning mechanism.
What is the function of a Shine-Dalgarno sequence in bacteria?
Provides ribosome binding site for translation initiation.
In which cellular compartment does translation occur in eukaryotes?
Cytoplasm
What is a characteristic of polycistronic mRNA molecules?
Encode proteins on different metabolic pathways.
What provides energy to cleave the polypeptide from the tRNA during termination of translation?
$GTP hydrolysis$
'Cistron' in bacteria refers to:
$DNA sequence$ that encodes a single polypeptide chain.
What is maintained throughout the process of translation?
Single reading frame
Test your knowledge on the termination of translation process and protein folding in ribosomes. Learn about the role of stop codons, release factors, GTP hydrolysis, and the recycling of ribosome subunits in terminating translation. Explore how polypeptide chains fold correctly as they exit the ribosome.
