What Are Chromosomes

The video explains the structure and function of chromosomes in eukaryotic cells. Chromosomes, made of tightly coiled DNA, fit into the cell nucleus and play a crucial role in cell division. They carry genetic information and vary in number across species. Humans have 23 pairs, while other species have different counts. Chromosomes have a centromere that divides them into arms, and during cell division, they duplicate to form sister chromatids. The video also highlights the importance of chromosomes in ensuring accurate DNA distribution during cell division.
