- A A structural protein component of the kinetochore complex structure
- B The synaptonemal complex (SC) that forms between homologs in Prophase I
- C A motor protein component of the meiotic spindle apparatus itself
- D A channel protein embedded within the nuclear pore complex structure
Correct answer: B. The synaptonemal complex (SC) that forms between homologs in Prophase I
Explanation: SYCP3 is a structural component of the lateral elements of the synaptonemal complex, the proteinaceous structure that holds homologs together during meiosis I.
