Question

8. Based on this information, scientist could predict that the base _______________________ pairs with _______________________ and the base _______________________ pairs with _______________________ in the formation of the DNA molecule. This is called complementary base pairs. Thus one strand of DNA is complementary to the other strand (opposite/matching).

Answer 1

Answer:

A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
