At which stage of mitosis, the two daughter chromatids separate from each other, migrate towards the opposite poles and are now referred to as chromosomes of the future daughter nuclei?

A

Prophase

B

Metaphase

C

Anaphase

D

Telophase

Text Solution

Verified by Experts

The correct Answer is:
C

In anaphase, the cetromeres of chromosomes start to divide into two, forming daughter chromosomes with centromere in each. Daughter chromosmes are repulsive, so they migrate towards opposite poles. Spindle fibles attached to the centromeres shorten and pull the chromosomes to the poles.

At what phase of meiosis are there two cells, each with separated sister chromatids that have been moved to opposite spindle poles ?

Two bar magnets are placed close to each other with their opposite poles facing each other. In absence of other forces, the magnets are pulled towards each other and their kinetc energy increases. Does it contradict our earlier knowledge that magnetic forces cannot do any work and hence cannot increase kinetic energy of a system?

Two poles of equal heights are standing opposite to each other on either side of the road, which is 120 feet wide. From a point between them on the road, the angles of elevation of the top of the poles are 60^(@) and 30^(@) respectively. Find the height of the poles and the distances of the point from the poles.

Two short bar magnets of length 1cm have magnetic moments 1.20 " Am"^(2) and 1.00 " Am"^(2) , respectively . They are kept on a horizontal table parallel to each other with their North poles pointing towards the south . They have a common magnetic equator and are separated by a distance of 20.0 cm. The value of the resultant horizontal magnetic induction at the midpoint O of the line joining their centers is ( Horizontal components of Earth's magnetic induction is 3.6 xx 10^(-5) Wb m^(-2) ).
