B. It is double-stranded, so each side serves as a template for a new strand.
C. It has enzymes built into the helix that makes a copy when needed.
D. It is held together mostly by hydrogen bonds, which are easy to open for replication.

Which statement about relative potential energy of electrons is correct? a. an electron in the 2 p orbital of the second electron shell has more potential energy than an electron in the 2 s orbital of the second electron shell. b. an electron in the 2 p orbital of the second electron shell has more potential energy than an electron in the 3 p orbital of the third electron shell. c. an electron in the 3 p orbital of the third electron shell has more potential energy than an electron in the 2 p orbital of the second electron shell.
