The Molecular Basis of Inheritance Flashcards
Frederick Griffith
Was studying pneumococcus bacteria that produces pneumonia
What kind of organisms are bacteria
Single celled prokaryotes
What organism did Frederick Griffith experiment on
Mice
How many strands of a bacterial species did Frederick Griffith find 
2
What are the two types of strains that Griffith discovered
S train and R Strain
The S in s strain means
Smooth
What does the R in the R strain stand for
Rough
S strain
Disease causing bacteria grew into smooth colonies and culture plants
R strain
Harmless patriot that grows into rough conloies
Which strain of bacteria killed the mice when it was injected
S strain
How many experiments did Griffith have
4
What was Griffiths first experiment
Rough strain injected
What was Griffith second experiment
Smooth strain injected
What was Griffiths third experiment
He killed smooth strain injected
What is Griffiths fourth experiment
Rough strain and heat killed smooth strain
What happens in Griffiths first experiment
The mouse lives
What happens in Griffith second experiment
The mouse dies
