Arthur Kornberg (1918- ) of the U.S. produced DNA in a test tube. F. Sanger (1918- ) of Britain developed sequencing procedure for proteins, and later for DNA
Biological Membranes and Transportpart II Passive transport: with the gradient – Water transport—aquaporins – Glucose transporters – Co-transport of chloride and bicarbonate Active transport: against the gradient – Transport ATPases – Ion channels
Functions of Nucleotides RNA and DNA components serving as energy stores for future use in phosphate transfer reactions. These reactions are predominantly carried out by ATP
The term carbohydrate derives from the fact that many of them have a formula that can be simplified to (CH2O)n. Some of these compounds are chemically modified, however, and do not fit the formula due to the modification
