What does it mean for a double helix of DNA to be antiparallel and complementary?
What will be an ideal response?
When the two strands in double-stranded DNA associate with each other, one strand runs 5' to 3' in one direction, the other strand runs in the same plane, but with a 3' to 5' orientation (antiparallel). Hydrogen bonding between strands occurs between adenines and thymines, and between cytosines and guanines, which are in turn called complementary base pairs.
