Question 1 of 10

Which shows a correctly paired DNA molecule?
OA. GAG TA
TGC AT
O B. ACG TA
TCG AT
C. ACG TC
TGC AT
O D. ACG TA
TGC AT

Answer 1

The correct pairing of DNA bases follows the rules of complementary base pairing. Option D (ACG TA, TGC AT) is the only one that shows a correctly paired DNA molecule.

Step-by-step explanation:

The correct pairing of DNA bases follows the rules of complementary base pairing, where adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). Based on this rule, the only option that shows a correctly paired DNA molecule is Option D (ACG TA, TGC AT). In this option, adenine pairs with thymine, cytosine pairs with guanine, and so on, forming a correctly paired DNA molecule.
