Frederick Griffith's experiment showed that genetic material could be transferred between different strains of bacteria, leading to a change in their characteristics. This transfer of genetic material is known as transformation, which was demonstrated when the nonvirulent strain of bacteria was transformed into a virulent one after being in contact with genetic material from the virulent strain.

What hypothesis did Giffith form from the results of his experiment?
Griffith thought that genetic information was passed along by proteins.http://wiki.answers.com/What_hypothesis_did_griffith_form_from_the_result_of_his_experiment#ixzz15y0eyO5L
What did Frederick discover?
Frederick Griffiths observed natural transformation for the first time, while he was searching for the pneumonia vaccine. He discovered that mixing a heat killed pathogenic strain of bacteria with a living nonpathogenic strain converted some cells into the pathogenic form.

What is the birth name of Fred Griffiths?
Fred Griffith's birth name is Fred Merrill Griffith.
Why was Frederick griffths important?
Frederick Griffiths was important for his pioneering work in genetics, particularly through his 1928 experiment with Streptococcus pneumoniae, which demonstrated the phenomenon of transformation. He discovered that non-virulent bacteria could acquire virulence when exposed to dead virulent bacteria, suggesting that some "transforming principle" was responsible for this change. His findings laid the groundwork for later research that ultimately identified DNA as the genetic material, significantly advancing our understanding of heredity and molecular biology.
When did Frederick griffith get married?
Yes, Richard Griffiths married to Heather Gibson in 1980
How might you use radioactive phosphorus to demonstrate that transforming compound of bacteria in Griffiths experiment was DNA?
In Griffith's experiment, the transforming principle was identified as DNA. To demonstrate this using radioactive phosphorus, one could label DNA with phosphorus-32, as DNA contains phosphorus in its backbone, while proteins do not. By introducing the radioactive DNA into non-virulent bacteria and observing the transformation into virulent forms, one could track the incorporation of the radioactive label. If the transformed bacteria contained radioactivity, it would indicate that DNA was the transforming material, supporting the conclusion that DNA carries genetic information.
What was the purpose of Griffiths 3 experiments in which he injected a mouse with live R S and heat killed S cells?
In Griffith's experiment 1 he injected the mouse with live R cells.It was not till Griffiths experiment 2 did he injest the mouse with live S cells.
What has the author Vernon Griffiths written?
Vernon Griffiths has written: 'An experiment in school music making' 'Twenty talks to children on musical subjects' -- subject(s): Instruction and study, Juvenile, Music
Why is the term appropriate given to Griffiths observations is transformation?
The term "transformation" is appropriate for Griffiths' observations because it describes the process by which genetic material from one organism can change the characteristics of another organism. In his classic experiments with Streptococcus pneumoniae, Griffith demonstrated that non-virulent bacteria could become virulent when exposed to heat-killed virulent strains, indicating a transfer of genetic information. This process of acquiring new traits through the uptake of foreign DNA is fundamentally what transformation entails in a biological context.
What was the significance of Fred Griffiths experiment?
Fred Griffith's experiment in 1928 demonstrated the phenomenon of transformation in bacteria, revealing that genetic information could be transferred between organisms. He used two strains of Streptococcus pneumoniae—one virulent and one non-virulent—and showed that the non-virulent strain could acquire the virulence factor from the heat-killed virulent strain. This experiment laid the groundwork for understanding the nature of genetic material, ultimately leading to the discovery of DNA as the molecule responsible for heredity. It was a pivotal moment in molecular biology and genetics.
