Question

Quizplus · Accepted Answer

All of the choices are correct. The strands in a double helix of DNA are antiparallel, meaning they run in opposite directions. They are also complementary, meaning the sequence of bases on one strand determines the sequence on the other strand. The two strands are held together via hydrogen bonds between the complementary base pairs (A-T and C-G). Finally, the double helix is wound around itself, with 10 base pairs per turn.
