How did Meselson and Stahl support Watson and Crick鈥檚 double-helix model? a. They demonstrated that each strand serves as a template for synthesizing a new strand of DNA.
b. They showed that the DNA strands break and recombine without losing genetic material.
c. They proved that DNA maintains a double-helix structure while undergoing semi-conservative replication.
d. They demonstrated that conservative replication maintains the complementary base pairing of each DNA helix.
