Nobel Prize 2015 – Chemistry


The Nobel Prize in the field of Chemistry for this year has been awarded to a trio of scientists for their enlightening research on DNA.

Tomas Lindahl (UK), Paul Modrich (USA) and Aziz Sancar (USA) were chosen by The Royal Swedish Academy of Sciences for their work in the field of DNA repair, which has led to new insights into different ways of curing cancer.


The scientists made independent investigations regarding natural mechanisms for DNA repair. Modrich discovered the process of mismatch repair, a mechanism used by cells to correct errors that occur during DNA replication.

Lindahl was responsible for revealing the molecular mechanism of base excision repair, which helps in sustaining life on Earth by preventing the continuous DNA damage caused by its high rate of decay.

Lastly, Sancar discovered the mechanism of nucleotide excision repair, used by cells to undo DNA damage due to UV rays and other toxins.

In its announcement the committee said that “The basic research carried out by the 2015 Nobel Laureates in chemistry has not only deepened our knowledge of how we function, but could also lead to the development of life-saving treatments,”.
