History of genetics of the fruit fly "Drosophila melanogaster". In 1928, Frederick Griffith showed that genes could be transferred. In what is now known as Griffith's experiment, injections into a mouse of a deadly strain of bacteria that had been heat-killed transferred genetic information to a safe strain of the same bacteria, killing the mouse. A series of subsequent discoveries led to the realization decades later that the genetic material is made of DNA (deoxyribonucleic acid). In 1941, George Wells Beadle and Edward Lawrie Tatum showed that mutations in genes caused errors in specific steps in metabolic pathways. This showed that specific genes
Myristic acid Myristic acid Myristic acid (IUPAC systematic name: 1-tetradecanoic acid) is a common saturated fatty acid with the molecular formula CH(CH)COOH. Its salts and esters are commonly referred to as myristates. It is named after the binomial name for nutmeg ("Myristica fragrans"), from which it was first isolated in 1841 by Lyon Playfair. Nutmeg butter has 75% trimyristin, the triglyceride of myristic acid. Besides nutmeg, myristic acid is also found in palm kernel oil, coconut oil, butterfat, 8–14% of bovine milk, and 8.6% of breast milk as well as being a minor component of many other animal fats. It is also
