Statement I: | DNA polymerases catalyse polymerisation only in one direction, that is 5' →3' |
Statement II: | During replication of DNA, on one strand the replication is continuous while on other strand it is discontinuous. |
Taylor conducted the experiments to prove semi-conservative mode of chromosome replication on:
1. Vinca rosea
2. Vicia faba
3. Drosophila melanogaster
4. E. Coli
Choose the correct pair from the following :
1. | Polymerases | - | Break the DNA into fragments |
2. | Nucleases | - | Separate the two strands of DNA |
3. | Exonucleases | - | Make cuts at specific positions within DNA |
4. | Ligases | - | Join the two DNA molecules |
The experimental proof for semiconservative replication of DNA was first shown in a:
1. Fungus
2. Bacterium
3. Plant
4. Virus
