Question

Force is defined as mass per unit acceleration. As the number of phosphate molecules increases, the charge also increases which increases the force required. The acceleration is dependent on the size of the molecules.

(a) True

(b) False

I had been asked this question in class test.

I want to ask this question from Gel electrophoresis, Oligonucleotide  & Microarrays topic in chapter Basics of Genetic Engineering of Genetic Engineering

Answer 1

Correct option is (b) False

To elaborate: As the charge increases, which is because of the number of phosphate molecules, the size also increases. As, the size increases, it also results in increase of mass. Thus, now the force and also the acceleration are independent of size until a retarding force is present. But, in the case of gel electrophoresis, the retarding force is provided by gel and thus separation takes place on the basis of size.
