The amount of thymine equals the amount of adenine in DNA.
Provided evidence that genetic material from one bacterial strain can be transferred to that of another strain.
He showed that the DNA from strain S cells could transform strain R cells.
Frederick Griffith in 1928 using two different types of the bacterium Streptococcus pneumoniae first demonstrated bacterial transformation.
Ostwald T. Avery's experiment was an extension of the works of Griffith's. Griffith's experiment using virulent and avirulent Streptococcus pneumoniae (which had different colony characteristics) proved that it was possible for the heat killed virulent Streptococcus pneumoniae to pass on the genetic information for formation of smooth colonies to avirulent strains. Avery, Mc Leod and Mc Carty conclusively found out that the genetic material responsible for transfer of characteristics between the strains was DNA. This was achieved by incubating the cell lysate of virulent Streptococcus with proteases, RNAses and DNAses separately before mixing it with avirulent strains. It was found that only when the lysate was incubated with DNAses did the transfer of smooth colony formation characteristic from the virulent strain to the avirulent strain fail to occur.
The scientist was Frederick Griffith, in 1928. Although he believed proteins were involved, it was actually the transfer of DNA. The harmless pneumonia bacteria acquired the DNA from the killed viruses, and became equally lethal.
Griffith' experiment in Biology refers to an experiment that tries discover the "transforming principle" in pneumococcus creatures.
Frederick Griffith introduced the Griffith experiment in 1928. This experiment proved that bacteria can carry genetic information through a process called transformation.
The amount of thymine equals the amount of adenine in DNA.
Bullseye killed them.
Bacteria exposed to DNA can incorporate the DNA and change phenotype.
