DNA is the genetic code for all living things on Earth. Place the following structures related to DNA in order from largest to smallest, with largest at the top and smallest at the bottom.

Answer 1

To order the structures related to DNA from largest to smallest, we typically have the following hierarchy:

1. Chromosome - The largest structure that contains many genes.
2. Chromatin - A complex of DNA and proteins that forms chromosomes; it exists in a more relaxed form when the cell is not dividing.
3. DNA double helix - The structure of DNA itself, consisting of two strands that coil around each other.
4. DNA nucleotide - The smallest unit of DNA, made up of a sugar, a phosphate group, and a nitrogenous base.

So the order from largest to smallest is:

1. Chromosome
2. Chromatin
3. DNA double helix
4. DNA nucleotide
