Oswald Avery - ️️Identified the substance causing bacterial transformation. We now know that the gene for the enzyme that catalyzes the synthesis of polysaccharide capsule, which makes the bacterial colony look "smooth," was transferred into the R cells during transformation. Nucleic acids - ️️polymers specialized for the storage, transmission, and use of genetic information. Two types- DNA and RNA. grow in the 3'-5' direction DNA - ️️macromolecule that encodes here...

1) In his transformation experiments, what did Griffith observe? A) Mutant mice were resistant to bacterial infections. B) Mixing a heat-killed pathogenic strain of bacteria with a living nonpathogenic strain can convert some of the living cells into the pathogenic form. C) Mixing a heat-killed nonpathogenic strain of bacteria with a living pathogenic strain makes the pathogenic strain nonpathogenic. D) Infecting mice with nonpathogenic strains of bacteria makes them resistant to pathogeni...

Frederick Griffith, 1928 didnt discover DNA. He injected mice with R and S (S=virulent). Then. He injected mice with living type R and heat-killed type S bacteria into the mouse. The living type R cells have been transformed inti virulent type S cells! A transforming substance for the S trait was passed feom S to R cells. Avery, MacLeod and McCarty, 1944 They showed that the transforming substance was DNA. -They purified any cells transddormed from R--->S and found that the tr...

Ch 51 AP Bio Practice Questions Rated A 1) During a field trip, an instructor touched a moth resting on a tree trunk. The moth raised its forewings to reveal large eyespots on its hind wings. The instructor asked why the moth lifted its wings. One student answered that sensory receptors had fired and triggered a neuronal reflex culminating in the contraction of certain muscles. A second student responded that the behavior might frighten predators. Which statement best describes these e...
