Question

A strand of DNA contains the bases adenine, cytosine, cytosine, and guanine, in that order. Which would be the order of the bases on the opposite strand of DNA?

cytosine, adenine, adenine, and thymine
cytosine, thymine, thymine, and adenine
thymine, guanine, guanine, and cytosine
thymine, adenine, adenine, and cytosine

Answer 1

It should be thymine, guanine, guanine, and cytosine.

Remember A(adenine) always goes with T(thymine) and C(cytosine) always goes with G (guanine)

The way i was taught was

Apples (adenine) in the trees (thymine)

Cars (cytosine) in the Garage (guanine)
