Calcium would be more reactive because it is closer to francium on the periodic table, francium is the MOST reactive element.
Answer:
I would say that it is the bond called complementary hydrogen bonds
Explanation:
The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.
It would be a chemical property
Answer: Positive charge
