	Frederick Griffith
		One was a virulent strain with a smooth polysaccharide coat necessary for infection and colonies of this strain appear smooth.
		Griffith took a heat-killed strain of the virulent bacteria and injected it into mice and observed that they did not die.
		Griffith's fourth experiment was to inject heat treated, killed, smooth virulent strain mixed with the non virulent rough strain.

	DNA Computing Examples
		Griffith’s experiments contained two strains of a type of bacteria commonly called pneumococci, which mainly caused his killer disease.
		The only physical difference Griffith could find was that the deadly strain had a smooth-coated surface made of sugar surrounding it, and the harmless strain had a rough-coated surface with nothing protecting it.
		Griffith believed that the harmful strain was unable to produce the smooth coat.

		Griffith theorized that some type of transformation had to take place from the virulent to the non-virulent strain for the non-virulent strain to synthesize a new polysaccharide coat.
		Griffith called this process a transformation and a transforming factor was Griffith's name for the unknown material leading to transformation.

	Frederick Griffith Summary
		Griffith was born in 1879 (some sources say 1877 or 1881) in Hale, in Cheshire, England, and he attended Liverpool University.
		When Griffith began his work, he knew that the difference in virulence was due to a polysaccharide coating, or capsule, on the Type III organisms which protected the bacteria from the host's immune system.
		Griffith was, in fact, trying to make a vaccine to prevent pneumonia infections in the epidemics after World War I.

		Frederick Griffith was born in 1881, died in 1941.
		He was a bacteriologist who discovered that if he put pathogenic (disease-causing) pneumococcus bacteria which had been killed by heat in with nonpathogenic pneumococcus bacteria which were alive, then the live, nonpathogenic bacteria would become pathogenic.

	Griffith's experiment
		In 1928, Frederick Griffith conducted an experiment that showed the transformation of living cells by a transforming principle, which was later discovered to be DNA.
		Griffith used two strains of Pneumococcus (which infects mice), a S (smooth) and a R (rough) strain.
		The S strain covers itself with a polysaccharide capsule that protects it from the host's immune system, resulting in the death of the host, while the R strain doesn't have that protective capsule and is defeated by the host's immune system.

		The bacteriologists were interested in the difference between two strains of Streptococci that Frederick Griffith had identified in 1923: one, the S (smooth) strain, has a polysaccharide coat and produces smooth, shiny colonies on a lab plate; the other, the R (rough) strain, lacks the coat and produces colonies that look rough and irregular.
		Griffith had discovered that he could convert the R strain into the virulent S strain.
		In their blood, Griffith found live bacteria of the deadly S type.

	REVIEW OF RELATED LITERATURE
		In 1928 a scientist named Frederick Griffith was working on a project that enabled others to point out that DNA was the molecule of inheritance.
		Griffith's experiment involved mice and two types of pneumonia, a virulent and a non-virulent kind.
		Griffith thought that the killed virulent bacteria had passed on a characteristic to the non-virulent one to make it virulent.

	[No title]
		Frederick Griffith was a British bacteriologist who worked with the bacteria that cause pneumonia.
		Griffith concluded that the live unencapsulated bacteria were transformed into live, encapsulated bacteria through interaction with the dead encapsulated bacteria.
		Griffith hypothesized that the substance responsible for this transformation of genetic material was a protein, and called it the “transforming principle.” Griffith’s work showed that bacteria could be transformed, but the method of transformation was still unknown.

	The Oswald T. Avery Collection: Shifting Focus: Early Work on Bacterial Transformation, 1928-1940
		Griffith showed that R and S strains could be converted from one to the other in living organisms as well as in the laboratory.
		Griffith's discovery initially meshed nicely with Avery's understanding of virulence: the smooth, virulent colonies were encapsulated, whereas the non-virulent strains had lost their capsules.
		As early as 1922, he arrived at the alternative theory that the virulence of types I and II were attenuated during convalescence, and that this change was accompanied by the mutation of type characters, which transformed and degraded the pneumococci into those of the heterogeneous and less virulent type IV.

	Griffith's Experiment
		In 1928 Frederick Griffith, in a series of experiments with Diplococcus pneumonia (bacterium responsible for pneumonia), witnessed a miraculous transformation.
		Griffith was surprised to find in his experiments that mice injected with a mixture of heat-killed S-strain and live but nonvirulent R-strain produced lethal results.
		The transformation witnessed by Griffith is a random and rare event.

	DNA Structure and Function
		Frederick Griffith performed an experiment using pneumonia bacteria and mice.
		Since Griffith had used heat to kill the bacteria and heat denatures protein, he next hypothesized that perhaps some protein within the living cells, that was denatured by the heat, caused the disease.
		Griffith concluded that the live R strain bacteria must have absorbed genetic material from the dead S strain bacteria, and since heat denatures protein, the protein in the bacterial chromosomes was not the genetic material.
