ALong chains of fatty acid units
BShort strands of transfer RNA
CPhosphate groups or small molecules
DCopies of the original gene
Answer & Solution
Correct answer: C. Phosphate groups or small molecules
1. Modification in the Golgi is followed by a separate tagging step.
2. The tags are phosphate groups or other small molecules.
3. Those tags are what let each molecule be routed to its proper destination.
4. Transfer RNA works at the ribosome during synthesis, so it plays no part in this sorting step.
5. The tags are phosphate groups or other small molecules.
