PPT-DNA LS 5.3 What is DNA? Deoxyribonucleic Acid

The hereditary material This is what you get from your parents and what is passed to offspring during reproduction A type of nucleic acid recall 4 main biological molecules A characteristic of all living things. Electronegativity of the atom attached to H the more EN the attached atom the more acidic the molecule C N O F relative electronegativity CH NH HO F relative stability of conjugate bases CH NH H O HF relative acidity 1 Charged vs noncharged H C CRICK AND J D WacsoNt Medical Research Council Unit for the Study of the Molecular Structure of Biological Systems Cavendish Laboratory University of Cambridge Communicated by Sir Lawrence Bragg FRSReceived 24 August 1953 Plate 21 This paper des By: Sheila Mulhern.
