Cell Cycle And Cell Division

Question
CBSEENBI11025501
Wired Faculty App

The complex formed by a pair of synapsed homologous chromosomes is called

  • equatorial plate

  • kinetochore

  • bivalent

  • axoneme

Solution

C.

bivalent

Synapsis is the pairing of homologous chromosomes. Each pair is called bivalent. Chromosomes line up around the equator of the spindle, attached by their centromeres to the spindle fibres, which are microtubules. The microtubules forming spindles can be of two types, i.e., kinetochore microtubule and non-kinetochore microtubule. 

Axoneme is the central core of a cilium or flagellum consisting of a central pair of filaments surrounded by nine other pairs.

Equatorial plate is the plane located midway between the poles of a dividing cell during the metaphase stage of mitosis or meiosis. It is formed from the migration of the chromosome to the centre of the spindle.
