What term refers to genetic information packaged into structures called DNA?

• A. Chromosomes
• B. Genes
• C. Chromatin
• D. Genome

Answer: (A)

Organizing genetic information into discrete units inside the cell is the idea here. DNA stores the information, but it’s packaged into specific structures that organize and segregate it. In eukaryotic cells, DNA wraps around histone proteins to form chromatin, and during cell division this chromatin condenses into chromosomes. Chromosomes are the carriers that hold the genetic information and the genes it contains, making them the term that best fits “genetic information packaged into structures.” The other terms describe parts of the system: genes are individual units on DNA, chromatin is the DNA–protein complex in its less condensed form, and the genome is the entire set of genetic material.
