A mixture containing DNA fragments a, b,...

A mixture containing DNA fragments a, b, c and d with molecular weigths of `a+b=c,a gt b` and `d gt c`, was subjected to agarose gel electrophoresis. The positions of these fragments from cathode to anode sides of the gel would be

A

b, a, c, d

B

a, b, c, d

C

c, b, a, d

D

b, a, d, c

Text Solution

Verified by Experts

The correct Answer is:
A
Agarose gel electrophoresis is a method to separate DNA or RNA molecule by size. This is achieved by moving negatively charged nucleic acid molecule through an agarose matrix within the electric field. Shorter molecule moves faster and migrates faster than longer ones.
