What was the key finding from Griffith's experiments using live and heat killed pathogenic bacteria?
1 Bacteria with a smooth coat could kill mice
2 Bacteria with a rough coat are not lethal
3 DNA is the genetic material
4 Genetic material can be transferred from dead to live bacteria
Explanation:
Griffith concluded that the R-strain bacteria must have taken up what he called a "transforming principle" from the heat killed \(S\) bacteria, which allowed them to "transform" in to smooth -coated bacteria and become virulent.

Who among the following scientists developed cytochemical technique for the presence of DNA
1 Johannsen
2 Hammerling
3 McClintock
4 Feulgen and Rossenbeck
Explanation:
Feulgen and Rossenbeck developed cytochemical technique for the presence of DNA.

Griffith in his experiment with Diplococcus pneumoniae discovered
1 r-DNA
2 transformation
3 gene expression
4 reverse transcription
Explanation:
The most important finding of Griffith's experiments with Pneumonia in rats was the finding that bacteria are capable of transferring genetic information through transformation.

In vitro synthesis of RNA and DNA was carried out first by :
1 Ochoa and Nirenherg
2 Ochoa and Kornberg
3 Nirenberg and Khorana
4 Kornberg and Nirenberg
Explanation:
During a research carried the span of more than sixty years. Ochoa and Kornberg made many outstanding contributions to molecular biology. He was the first to isolate DNA polymerase, the enzyme that assembles DNA from its components, and the first to synthesize DNA in a test tube, which earned him a Nobel Prize in 1959.
