Document Summary
Thermodynamics: a reacting system not at equilibrium will tend to move toward equilibrium. The magnitude of movement can be expressed as the free energy change (change in. Delta g tells us why direction the reaction will want to go. First step of glycolysis is attaching a phosphate which will become an unfavorable reaction. The dna itself, not the proteins are responsible for heredity. S-strain doesn"t kill the mouse but when you mix the s-strain heat-killed with the r strain, the mouse dies. The dna destroyed from the s-strain extract meant that the. The hershey-chase experiment: nailed down the idea that dna was hereditary material. Found that the radioactivity was recovered in the bacteria when we labeled the. T2 phage"s proteins with radio-labels while radioactivity was recovered in the cell itself when we labeled the t2 phage"s dna with radio labels.
