Biology Question on cell cycle and cell division
Chiasmata are first seen during
A
leptotene
B
diplotene
C
zygotene
D
pachytene.
Answer
diplotene
Explanation
Solution
During diplotene stage, the nucleoprotein fusion complex of the synapsed chromosomes dissolve partially. Due to this, the points of attachment between the homologous chromosomes known as chiasmata are distinctly seen. Chiasmata may be terminal or interstitial and depending upon their position, the homologous chromosomes appear cross-like, ring-like or chain-like.
