Question

genetic variation from errors quick check
which statement about chromosomes is true? (1 point)
chromosomes are found in sets of three.
dna contains chromosomes.
chromosomes contain dna.
the same number of chromosomes appears in haploid and body cells.

Explanation:

Chromosomes are structures within cells that carry genetic information. They are made up of DNA and proteins. DNA is the molecule that contains the genetic instructions for the development, functioning, growth, and reproduction of all known organisms. So, chromosomes contain DNA.
Haploid cells (like gametes) have half the number of chromosomes as body (somatic) cells. Chromosomes are usually found in pairs (diploid organisms) not sets of three. And it's chromosomes that contain DNA, not the other way around.

Answer:

Chromosomes contain DNA.
