Question

Match column I with column II and select the correct option from the given codes

Sr.no	List I	Sr.no	List II
a.	V-shaped at anaphase	1.	Acrocentric chromosome
b.	L-shaped at anaphase	2.	Metacentric chromosome
c.	J-shaped at anaphase	3.	Telocentric chromosome
d.	I- shaped at anaphase	4.	Sub-metacentric chromosome

.

• A. A-(iv),B-(ii),C-(i),D-(iii)
• B. A-(ii),B-(iv),C-(i),D-(iii)
• C. A-(ii),B-(iv),C-(iii),D-(i)
• D. A-(iv),B-(iii),C-(ii),D-(i)

Answer 1

The correct option is B A-(ii),B-(iv),C-(i),D-(iii)

Anaphase is a stage where the chromosomes split from the middle and two chromatin get separate and both the chromatids move toward opposite poles due to a repulsive force which is known as an aphasic moment.

The different shapes of chromosome become evident during chromosome movement that is metacentric, acrocentric et cetera. If the chromosome is V-shaped at anaphase then it would be metacentric because it is from the exact centre of the centromere.

If it is L shaped at anaphase then it will be submetacentric because one arm would be smaller than the other arm. If it is J shaped then it is acrocentric chromosome because it is on one end of the chromosome and if it is I shaped then it is telocentric

So, the correct option is 'A-(ii),B-(iv),C-(i),D-(iii)'
