During karyokinesis, the spindle fibres get attached to condensing chromosome at a highly differentiated region. This region is called as

Options

A. chromocentre
B. kinetochore
C. centriole
D. chromomere

Answer

B

Explanation

During late prophase, specialised structures called kinetochores develop on either surface of the centromere. Chromosomal fibres get attached to kinetochore.Charomomeres are beaded structure on the chromosomes which are found particularly at the prophase-I (particularly at leptotene ) of meiosis -I.
Chromocentric is developed due to the fusion of centromeric regions of all the chromosomes of a cell. Centrosome is found in animal cells(absent in higher plant cells). It is found near the nucleus. Each centrosome is made up of two centrioles and each centriole is a cylindrical structure with a diameter of ` 1500 - 1800 Å` and is made up of nine fibrils.
