Recall the basic structure and composition of chromosomes in cells.
Understand that chromosomes are primarily composed of nucleic acids and proteins.
Identify that DNA (deoxyribonucleic acid) is the main nucleic acid found in chromosomes, carrying genetic information.
Recognize that proteins, especially histones, are associated with DNA to help package and organize it within the chromosome.
Conclude that the two primary chemical components making up chromosomes are DNA and proteins.
