Chromosomes: The Carriers of Genetic Blueprints

The video tutorial explains that genes are located on chromosomes, which are made of DNA coiled around proteins. Chromosomes allow large DNA molecules to fit into a cell's nucleus. Humans have 23 pairs of chromosomes, with one chromosome from each parent. This genetic inheritance may explain familial resemblance. The video concludes with a review and quiz questions about chromosome composition and quantity in human cells.
