8.1 DNA Flashcards
What was the first step of Griffith’s experiment?
Infect a mouse with a smooth strain of DNA, and find out that it dies.
What was the second step of Griffith’s experiment?
Infect a mouse with a rough strain of DNA, and find out that is lives.
What was the third step of Griffith’s experiment?
Infect a mouse with a heat killed smooth strain of DNA, and find out that it lived.
What was the fourth step of Griffith’s experiment?
Infect a mouse with a combination of the rough strain and heat killed smooth strain, and find out that it dies.
What was the conclusion of Griffith’s experiment?
A transformation occurred giving the rough strand something from the heated smooth strand.
What was the first step of Avery, MacLeod, and McCarty’s experiment?
Infect a mouse with a combination of the rough strain and heat killed smooth strain, and find out that it dies.
What was the second step of Avery, MacLeod, and McCarty’s experiment?
Infect a mouse with a combination of the rough strain and heat killed smooth strain, but without proteins, and find out that it dies.
What was the third step of Avery, MacLeod, and McCarty’s experiment?
Infect a mouse with a combination of the rough strain and heat killed smooth strain, but without RNA, and find out that it dies.
What was the fourth step of Avery, MacLeod, and McCarty’s experiment?
Infect a mouse with a combination of the rough strain and heat killed smooth strain, but without DNA, and find out that it lives.
What was the conclusion of Avery, MacLeod, and McCarty’s experiment?
DNA was the transforming material that made the substance deadly.
What was the first step of the Hershey-Chase experiment?
Put radioactive phosphorus into the DNA of one virus, and radioactive sulfur into the protein coat of another.
What was the second step of the Hershey-Chase experiment?
Infect bacteria with each of the viruses.
What was the third step of the Hershey-Chase experiment?
Blend the mixtures to separate the viruses from the bacteria.
What was the fourth step of the Hershey-Chase experiment?
Bacteria infected with the DNA virus contained DNA markers, while bacteria infected with the protein virus contained no markers.
What was the conclusion of the Hershey-Chase experiment?
DNA is the transforming material because it made it into the bacteria.
What are the three parts of a nucleotide?
The phosphate, the oxyribose (sugar), and the nitrogenous base.
What is the structure of DNA?
DNA is antiparallel, with the 5’ end by the phosphorus, and the 3’ end by the OH
