Arrange the following from smallest to largest: DNA, Gene, Chromosome

A.Chromosome, Gene, DNA

B.Gene, DNA, Chromosome

C.Chromosome, DNA, Gene

1 answer

The correct arrangement from smallest to largest is:

B. Gene, DNA, Chromosome

To clarify:

  • A DNA molecule is a long chain of nucleotides.
  • A gene is a segment of DNA that contains the instructions for making a protein or RNA molecule.
  • A chromosome is a structure that organizes and compacts DNA, consisting of several genes.

So, in the context of size: Gene < DNA < Chromosome.
