With the help of Griffith's experiment, explain the DNA is the genetic material. What is the sigmnificance of DNA fingerprinting?

Hershey and Chase used which virus to prove that DNA is genetic material and infective part of virus?

Recall the experiment done by Frederick Griffith. If RNA, instead of DNA was the genetic material, would the heat killed strain of strep have transformed the R-strain into virulent strain? Explain your answer.

How did Hershey and Chase proved that DNA is the hereditary material? Explain their experiment with suitable diagram.

Explain DNA as a genetic material with the help of Harshey and Chase experiment.

How did Hershey and Chase differentiate between DNA and protein in their experiment while proving that DNA is the genetic material?

Go though the following statements (i) Meselson & stahl used cesium chloride density gradient to distinguish heavy DNA molecules from the normal DNA molecules. (ii) In meselson & Stahl experiment the DNA that was extracted from the culture one generation after the transfer from .^(15)N to .^(14)N , was composed of equal amount of hybrid (intermediate) DNA and of light DNA. (iii) In prokaryotes, control f the rate of transcriptional initiation is the predominant site for control of gene expression. (iv) In lac operon, the repressor is synthesised only at the time when the level of metabolite is in excess. Find out the correct statements?
