Structure Of DNA Quizzes & Trivia

The structure of DNA is composed of two strands with complementary base pairing, allows cells to do this easily. The two strands can separate, with each strand serving as a template to generate a new complementary strand. Test out what more you know about the structure and function of DNA through this test!
