RNAi technique is helpful in preventing the infestation of roots in tobacco plants. This can be done by introduction of nematode-specific genes using the Agrobacterium vectors into the host plant. The introduction of DNA was such that it produced both sense and anti-sense RNA in the host cells. These two RNA’s being complementary to each other formed a double stranded (dsRNA) that initiated RNAi and thus, silenced the specific mRNA in the nematode. The consequence was that the parasite could not survive in transgenic host expressing specific interfering RNA. The transgenic plant therefore got itself protected from the parasite.

In the 2nd century, the ancient physician Galen wrote that blood is created in the liver from ingested food and flows to the right side of the heart. He thought some of it flows then to the lungs where it gives off vapors, and some flows through pores into the left side of the heart, where it gains "vital spirits". Several arteries flow into the base of the brain, where those vital spirits are changed to animal spirits before being distributed to the rest of the body through hollow tubes called nerves. In the body tissues, blood is consumed. Amazingly, this canon held for nearly 1500 years, with only a few overlooked objections in the 1200s from Arab physician Ibn al-Nafis. (Nafis looked for the pores connecting the sides of the heart and couldn't find them; he also elucidated the pulmonary circulation.) In 1628, William Harvey realized something was amiss with this thinking. Now you can duplicate the process by which Harvey determined that blood flows through the body in a closed loop. Take your resting pulse and heart rate at rest. Recall the average stroke volume of a healthy individual. a) About how long will it take your heart to pump your entire body weight in blood? (10 pts) (you can estimate all of these numbers, just use values for the average human) b) Under Galen's version of the circulation, how much new blood would the liver need to produce each day? (10 pts)
