Prove that DNA replication is a semi-conservative process with the help of Meselson and Stahl experiment.

How is DNA replicated through semi-conservative process?

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

What is 'semi- conservative' DNA replication ? How was it experimentally proved and by whom ?

If DNA replication is conservative, what woul be expected distribution of labelled DNA molecule after two generations.

(a) Write what DNA replication refers to. (b) State the properties of DNA replication model. (c ) List any three enzymes involved in the process along with their functions.

Who proved the semi conservative nature of DNA replication?

What do you mean by semi-conservative replication? Mention the following in DNA replication : RNA-Primer

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?

Semi conservative replication of DNA was first demonstrated in

The experimental proof for semi-conservative replication of DNA was first shown in a
