Question

Quizplus · Accepted Answer

The synaptonemal complex is a protein structure that forms between homologous chromosomes during meiosis. Its main function is to hold the homologous chromosomes together, promoting and stabilizing interactions between homologous chromosomes. It also facilitates the exchange of genetic material between the chromosomes during crossing-over. Therefore, it functions primarily as a scaffold to allow interacting chromatids to complete crossover activities.

Therefore, option C is the best choice.
