Research into DNA has had a significant impact on medicine. Through recombinant DNA technology, scientists can modify microorganisms so that they become so-called factories that produce large quantities of medically useful drugs. This technology is used to produce insulin, which is a drug used by diabetics, and interferon, which is used by some cancer patients. Studies of human DNA are revealing genes that are associated with specific diseases, such as breast cancer. This information is helping physicians to diagnose various diseases, and it may lead to new treatments. For example, physicians are using a technology called chimeriplasty, which involves a synthetic molecule containing both DNA and RNA strands, in an effort to develop a treatment for a form of hemophilia.
Forensic science uses techniques developed in DNA research to identify individuals who have committed crimes. DNA from semen, skin, or blood taken from the crime scene can be compared with the DNA Of a susp

This has led to the theory that perk-laden executives are likeliest to be found in firms with lots of cash. but few investment prospects.
But in a recent paper, Raghuram Rajah, the IMF’s chief economist, and Julie Wulf, of the Wharton School, looked at how more than 300 big companies dished out perks to their executives in 1986-99. (47) It turns out
