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...

1. Griffith's experiments with heat killed pathogenic bacteria and live non-pathogenic bacteria indicated something from the dead bacteria could do something to the living, non-pathogenic bacteria that he called transfor- mation. What changes were observed in colony appearance and pathogenic- ity?: When the heat-killed S cells were mixed with the living R cells they combined and formed living S cells- smooth encapsulated cells 2. What biological macromolecule did Avery, McCarty, and MacLeod i...

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. 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). Hershey-Chase __________ are viruses that infect bacterial cells. Bacteriophages ______ discovered the relationships between D...

Hershey and Chase performed an experiment in order to determine how bacteriophages infect bacteria. What did they find? The bacteriophage injects DNA into the host cell. This was found because, after centrifugation, the pellet was radioactive The largest difference between a Gram + and Gram - bacterial cell is: The gram + cell has a much thicker peptidoglycan layer Why does a Gram + cell stain blue/purple in a gram stain? The Gram + cell stains blue/purple because crystal violet rem...

BIO 111 TAMU Fletcher Exam 3 Questions And Answers 100% Solved | Graded A+ 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 - per...
