Honey, What Did the Doctor Say?

A middle aged man goes into the doctor's office for a check-up with a litany of complaints. The doctor speaks to the man’s wife alone and says, "There is nothing the matter with your husband. If you make a couple of meals for him a day, let him watch his sports. Do not complain at him too much and require him to listen. Limit his exposure to in-laws and make love to him once a week. Then, he’ll probably live another 20 years."She returns to her husband’s side in the waiting room. He asks,
"What did the doctor tell you?"
"You are going to be dying soon, my dear."

Phoebus Levene

Born 25 Feb 1869; died 6 Sep 1940 at age 71.Phoebus Aaron Theodor Levene was a Russian-American chemist who was a pioneer in the study of nucleic acids. In 1909, he found that the carbohydrate present in nucleic acid from yeast is the pentose sugar ribose. In 1929, he succeeded in identifying the carbohydrate in the nucleic acid from the thymus of an animal. It is also a pentose sugar but lacks one oxygen atom of ribose and was therefore called deoxyribose. These were named ribonucleic and deoxyribonucleic acids (RNA and DNA). Levene also determined how the nucleic acid components combine to form the nucleotides and how the nucleotides combine in chains. Later discoveries showed DNA and RNA to be key elements in the maintenance of life.
