👤 whose
Whose work first identified telomeres as protective chromosome ends?
Human BiologyGenetics
Quick Answer
Elizabeth Blackburn, Carol Greider, and Jack Szostak showed how telomeres protect chromosomes and how telomerase extends them. Their work earned the 2009 Nobel Prize in Physiology or Medicine.
The Full Story
Elizabeth Blackburn, Carol Greider, and Jack Szostak discovered that chromosome ends are capped by telomeres, which protect genetic material during replication. They also identified telomerase, the enzyme that rebuilds telomeres. Their findings explained how chromosomes avoid losing important DNA with each cell division. The discovery became central to aging research, cancer biology, and genome stability.
Key Facts
1.They won the 2009 Nobel Prize
2.Telomeres are repetitive DNA at chromosome ends
3.Telomerase helps maintain telomeres
