In the double helix model proposed by Watson and Crick, one strand runs 5' to 3' while the other runs 3' to 5'. This orientation is necessary for which process?
Q1. In the double helix model proposed by Watson and Crick, one strand runs 5' to 3' while the other runs 3' to 5'. This orientation is necessary for which process?
Answer: Hydrogen bond formation
Explanation: Antiparallel strands allow nitrogenous bases to align properly for hydrogen bonding. Phosphodiester linkages occur within a single strand, regardless of direction.
