Which of these is paired correctly?
A
Adenine-GuanineCytosine-Thymine/Uracil
B
Adenine-CytosineGuanine-Thymine/ Uracil
C
Adenine-Thymine/ UracilCytosine-Guanine
D
Adenine-UracilCytosine-Guanine/ Thymine
Explanation: 

Detailed explanation-1: -Base Pair Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G) [GWA-NeeN] or thymine (T). The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.

Detailed explanation-2: -Adenine (A) is always supposed to pair with thymine (T), and cytosine (C) is always supposed to pair with guanine (G). The two “Watson-Crick” base pairs, A-T and C-G, form the DNA sequences of all life as we know it.

Detailed explanation-3: -Answer and Explanation: The correct answer: The RNA base which pairs with the adenine in DNA is D. Uracil. Adenine base pairs with thymine in the case of a DNA molecule, but the base thymine is replaced by uracil residues in the case of RNA.
