Answer:

A

Explanation:

Gel electrophoresis is an amazing technique that allows for DNA separation based on size (as in, length). Using electricity (and keeping in mind that DNA has a negative charge because of the phosphate groups), the shortest pieces will migrate the farthest.

So we can tell that the pieces are in ascending order of size. 4>3>2>1, in length.

A. Strand 1 is the smallest.

Answer:Given results of gel electrophoresis shows that strand 1 is smallest. The pieces are arranged in ascending order of size 4>3>2>1 . Thus,option A is correct.

Explanation:

What is Gel electrophoresis?

Gel electrophoresis is a laboratory technique used to separate mixture of DNA ,RNA or protein according to their molecular size.

The gel used in this technique is composed of polyacrylamide or agarose.

The main application of gel electrophoresis has been in the seperation of molecules and in restriction mapping.

The main advantage of gel electrophoresis is its capability to

simultaneously separate various samples in one round.

Therefore, strand 1 is the smallest according to the result of gel electrophoresis  shown in figure. Thus, option A is correct.
