USABO Questions with Correct Answers In the extracellular matrix of an animal cell, you would like to test the binding partner of integrins in vitro. Integrins would most likely require firm attachment to which of the above option? - Answer-Actin You are working with Dr. Lee at University of Wisconsin-Madison to investigate cytokinesis in a newly discovered marine worm. You generated antibodies to conserved proteins involved in cell division in other organism to look for proteins that loc...

Friedrich Miescher - discovered DNA in 1869 But did not know (Isolated phosphate) rich acidic compounds Frederick Griffith - Discovered transformation during an experiment that involved injecting mice with smooth S cells, rough R cells, heat-killed S cells, and heat-killed S cells with living R cells. Avery, MacLeod, McCarty - Identified the heritable substance as DNA Used test tubes- vitro Hershey and Chase - performed experiments showing that DNA is the genetic material of a phage known...

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...

biology 1406 exam 5 Collin College - Question and answers already passed biology 1406 exam 5 In 1928, __________ was surprised to find that when he killed pathogenic bacteria, then mixed the bacterial remains with living harmless bacteria, some living bacterial cells became pathogenic. - correct answer Frederick Griffith In 1952, ___________ used bacteriophages to show that DNA is the genetic material of T2, a virus that infects the bacterium Escherichia coli (E. coli). - correct an...

The negatively charged components of atoms are referred to as - electrons A young girl is staring at the raindrops running down her window. She notices that the raindrops remain more or less intact, even as they cascade down the windowpane. This is a result of - hydrogen bonds between water molecules With 4 distinct nucleotides, how many combinations are possible in a sequence of 6 nucleotides - 4096 Amino acids can be spontaneously generated in vitro (in a laboratory), but only - under an...

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...

genetic material must meet what criteria ANSWER: -information -replication -transmission -variation what happened in the late 1800s ANSWER: -biochemical basis -chromosomes carry genetic information what happened in the 1920s to 1940s ANSWER: -protein portion of chromosomes to be the genetic material explain Griffith's bacterial transformation ANSWER: -late 1920s Frederick griffith - streptococcus pneumoniae - staring that secrete capsules look smooth (fatal in mice) Deeagles - S...
