LIFE SCIENCE

Detailed explanation-1: -DNA barcoding uses a genetic fragment of roughly 650 base pairs-the “barcode”-that is taken from a standard position in an animal’s genome. Barcodes have been effective in identifying animal DNA as belonging to a particular species; they thus allow scientists to identify organisms and specimens using genetic material.

Detailed explanation-2: -How does DNA fingerprinting help preserve endangered species, such as elephants? Poachers kill elephants for their tusks, but officials can use genetic information to identify the herds from which the poached elephants came from, and better police those areas.

Detailed explanation-3: -Project Tiger is a Tiger conservation programme launched in 1973 by the Government of India. The project aims at ensuring a viable population of Bengal tigers in their natural habitats and also to protect them from extinction, and preserving areas of biological importance as a natural heritage.

Detailed explanation-4: -Protect tigers and their habitat. Build capacity in range states. Reduce human-tiger conflict. Conduct scientific research on tigers to help inform conservation strategies. Promote tiger-friendly policies. Monitor tiger numbers, population trends, and threats to tigers and their habitats.
