Question

A mixture containg 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

Answer 1

hello dear friend...
good morning...

the DNA fragments which has lower molecular weight move than those have higher molecular weight. so the position of these fragments would be d - c - a - b.

hope it will help you...
best wishes...
