Nobel prize for chromosome find

This year’s Nobel prize for medicine goes to the three US researchers who discovered how the body protects the chromosomes housing vital genetic code.

Elizabeth Blackburn, Carol Greider and Jack Szostak jointly share the award.

Their work revealed how the chromosomes can be copied and has helped further our understanding on human ageing, cancer and stem cells.

The answer lies at the ends of the chromosomes – the telomeres – and in an enzyme that forms them – telomerase.

The 46 chromosomes contain our genome written in the code of life – DNA.

When a cell is about to divide, the DNA molecules, housed on two strands, are copied.

But scientists had been baffled by an anomaly.
