In 1950‚ Erwin Chargaff found that the arrangement of nitrogen bases in DNA varied widely‚ but the amount of certain bases always occurred in a one-to-one ratio. In the early 1950s‚ there was a race to discover DNA among scientists. At Cambridge University‚ Francis Crick along with James Watson showed a great interest and were impressed by Pauling ’s work. Meanwhile in London‚ Maurice Wilkins and Rosalind Franklin were also studying DNA. The Cambridge team ’s approach was to make physical models

Biology Exam Review Unit One – Biochemistry What is an isotope? Isotope - An isotope is all atoms of the same element that have the same number of protons‚ but they may have different numbers of neutrons in the nucleus. - This means that all atoms with the same atomic number can have different atomic masses. - Because they have the same number of protons and electrons‚ they behave exactly the same in chemical reactions. Radioisotope - The nuclei of some isotopes of an element are unstable

Big Idea 2 Biological systems utilize free energy and molecular building blocks to grow‚ to reproduce and to maintain dynamic homeostasis. Living systems require both free energy and matter to maintain order‚ grow and reproduce. Organisms employ various strategies to capture‚ use and store free energy and other vital resources. Energy deficiencies are not only detrimental to individual organisms; they also can cause disruptions at the population and ecosystem levels. Biological systems must both
