Answer #1

Antiparallel strands of DNA are important because:

1. Antiparallel strands are more stable than parallel strands.

2. Watson-Crick pairing is only possible between two strands when they are antiparallel.

3. Proton abstraction group of nitrogenous bases will remain exposed in parallel strand.

4. Major and minor groups are not possible in parallel strands.

5. DNA replication involves antiparallel strands out of which one is leading and another is lagging. Strand.

6. Double helical structure will be compromised in case of loss of antiparallel strands.
