DNA Repair Mechanism – Part I Introduction (DNA Damaging Agents, DNA Damages and Recovery of DNA Damages)

DNA Repair Mechanism

“Genetic variation is important for evolution, but the survival of the individuals demand genetic stability” DNA is the genetic information carrier molecule in the cell and thus it is very essential to keep the genetic information intact. Even though DNA holds a prime position, it is one of the highly susceptible molecules in the cells … Read more

Artemisinin is an anti-malarial parasite drug extracted from a Chinese medicinal plant called sweet wormwood (Artemisia annua; Asteraceae family). It is also known as qinghaosu in Chinese and it is the most rapid acting drug currently available against the malarial parasite, Plasmodium falciparum.

The 2015 Nobel Prize in Physiology and Medicine is shared by William C. Campbell, Satoshi Omura and Youyou Tu for the discoveries of therapies against parasitic infections which saved millions of life over the globe. Among the three Nobel laureates, Professor Youyou Tu of China shares half of the Prize money for the credit of isolation, purification and structure elucidation of Artemisinin, the anti-malarial parasite drug for the first time from a Chinese traditional medicinal plant Artemisia annua. Professor Tu is the first China based Woman scientist to win the science Nobel.
