Griffith - transforming principle - streptococcus pneumonia - virulent strain has polysaccharide coat, have smooth coat (S) - R= rough, avirulent (lack coat) - some R could become S spontaneously Avery, MacLeod, McCarty - isolated transforming principle - destroyed different components, one at a time, to pinpoint which component was responsible for transforming DNA - found that DNA contained genetic material Hershey and Chase - T2 bacteriophage - radioactivity - protein ...

G1 Phase correct answer: Preparation for DNA synthesis. Duplicate organelles and systolic compents. (8-10hrs) Cyclin D / CDK 4/6 Checkpoint close to end (RB). S phase costs a lot of ATP. S Phase correct answer: Interphase. DNA replication/synthesis. (6-8 hrs) Cyclin A / CDK2 Between G1 and S correct answer: Cyclin E / CDK2 G2 Phase correct answer: Cell growth to accomodate splitting, enzyme and protein synthesis continue; replication of centrosomes complete. (4-6hrs) Cyc...
