1. Conservative model.
2. Semiconservative model.
3. Dispersive model.
4. Destructive model.
Which scientist experimentally proved that DNA is the sole genetic material in bacteriophage?
1. Beadle and Tatum
2. Messelson and Stahl
3. Hershey and Chase
4. Jacob and Monod
Semiconservative replication of DNA was first demonstrated in:
1. Drosophila melanogaster
2. Escherichia coli
3. Streptococcus pneumoniae
4. Salmonella typhimurium
A molecule that can act as a genetic material must fulfill all the following criteria except:
1. It should be able to generate its replica.
2. It should chemically and structurally be stable.
3. It should be able to express itself in the form of Medelian characters.
4. It should provide scope for rapid changes required for evolution.
