Question

extension questions 14. other polar molecules include nucleic acids and some proteins. look at the dna sketch provided and predict how the two strands are attracted to one another.

Explanation:

DNA strands have complementary base - pairing. Adenine (A) pairs with Thymine (T) via two hydrogen bonds, and Guanine (G) pairs with Cytosine (C) via three hydrogen bonds. These hydrogen bonds are the main force attracting the two strands to one another.

Answer:

The two strands of DNA are attracted to one another by hydrogen bonds formed between complementary base pairs (A - T and G - C).
