Question

What Is Synapsis In Zygotene?

Answer 1

Synapsis in Zygotene:

1. Zygotene is the second phase in meiosis prophase-1.
2. It precedes by leptotene stage, during which chromosomes uncoil and condense.
3. During zygotene, homologous pairs begin to coordinate along their whole length by a precise process termed synapsis.
4. The synaptonemal complex is formed by ribbon-like protein that holds every pair of chromosomes together.
5. Pairs of chromosomes then become compacted and coiled during pachytene.
