ARemoval of the terminal amino acid
BAddition of short chains of sugars
CAttachment of a fatty acid chain
DCleavage into two smaller chains
Answer & Solution
Correct answer: B. Addition of short chains of sugars
1. As proteins and lipids travel through the Golgi they undergo further modifications that allow them to be sorted.
2. The most frequent of those modifications is the addition of short chains of sugar molecules.
3. Only after that are they tagged for routing to their proper destinations.
4. Cleavage into smaller chains is not among the Golgi modifications described, so that answer invents a step.
5. Adding short sugar chains is the most frequent modification.
