I WONDER - What Are Chromosomes?

DNA, or deoxyribonucleic acid, is a long molecule that contains our unique genetic code, acting as a blueprint for organism development, survival, and reproduction. DNA is organized into genes, which are packed into chromosomes. Humans have 23 pairs of chromosomes, totaling 46. Each gene carries instructions that determine traits such as eye color and hair type.
