Cell Cycle and Cell DivisionHard
Question
During cell division, the spindle fibres attach to the chromosome at a region called
Options
A.chromocentre
B.kinetochore
C.centriole
D.chromomere
Solution
During late prophase, specialised structures called kinetochores develop on either sufsce of the centromere. Chromosoma fibres get attached to kinetochore .
Chromomeres are beaded structures on the chromomeres which are found articularly at the prophase_I. (particurarly at leptotene) of meiosis -I.
Chromocentre is developed due to the fusion of centromeric regions of all the chromosomes of a cell.
Centrosome is found isn animal cells (absent in higher plant cells).
It is found near the nucleus .Each centrosome is made up of two centriolles and each centriole is a cylindrical structure with a diameter of 1500-1800
and is made up of nine fibrils.
