Part 3: Structure of a Chromosome

Chromosomes are more than just DNA — they are precisely organized structures that control how your body grows, repairs itself, and ages. In this educational science video, we break down chromosome structure, including arms, centromeres, and telomeres, and explain how their design directly affects cell division, aging, and disease risk. Watch Complete Playlist:    • Sexual health   You’ll learn: 00:00 What chromosomes are made of 00:07 Why structure determines biological function 00:12 How telomeres protect DNA and influence aging 00:22 Why does damage to chromosomes increase disease risk? This video is created for English-language audiences in the USA, UK, Europe, Australia, Singapore, and viewers worldwide who want clear, research-based explanations of human biology. If you’re interested in genetics, health science, aging, or how the human body really works, this channel delivers fact-driven content without hype. Comment if you’ve heard of telomeres before.
