A mixture containing DNA fragments a, b, c and d with molecular weights of a + b = - Biology - Biotechnology and its Applications

Question

A
mixture containing DNA fragments a, b, c
and
d with
molecular weights of a + b = c, a > b
and
d >
c, was subjected to agarose gel
electrophoresis
The
positions of these fragments from cathode
to
anode
sides of the gel would be
(1) b,
a, c, d (2) a, b, c, d
(3) c,
b, a, d (4) b, a, d, c

I think the options given by you are not correct Kindly, check
them and then do get back to us
Its true that movement of DNA fragments takes place from
cathode( negative electrode) towards anode(positive electrode) in
gel electrophoresis as DNA is negatively charged molecule
DNA fragments of lower molecular weight move farther than higher
molecular weight fragments So, the correct answer is
d-c-a-b order from cathode to anode according to
given conditions in the question

A mixture containing DNA fragments a, b, c and d with molecular weights of a + b = c, a > b and d > c, was subjected to agarose gel electrophoresis. The positions of these fragments from cathode to anode sides of the gel would be (1) b, a, c, d (2) a, b, c, d (3) c, b, a, d (4) b, a, d, c

A mixture containing DNA fragments a, b, c and

d with molecular weights of a + b = c, a > b and

d > c, was subjected to agarose gel electrophoresis.

The positions of these fragments from cathode to

anode sides of the gel would be

(1) b, a, c, d (2) a, b, c, d

(3) c, b, a, d (4) b, a, d, c
