Question

agarose gel electrophoresis separates dna molecules based on size in

a. centimeters
b. millilitres
c. base pairs
d. grams

Explanation:

Agarose gel electrophoresis is a technique used in molecular biology. DNA is a nucleic acid composed of nucleotides. The size of DNA molecules is measured by the number of base pairs (bp) they contain. Centimeters measure length in the metric system for macroscopic objects. Millilitres measure volume. Grams measure mass. Since DNA is a biological macromolecule made up of base - pair units, its size in the context of agarose gel electrophoresis (a technique for DNA separation) is described in base pairs.

Answer:

C. base pairs
