Which option correctly describes Watson-Crick base pairing in double-stranded DNA?
A
A pairs with C, and G pairs with T.
B
A pairs with G, and C pairs with T.
C
A pairs with T, and G pairs with C.
D
A pairs with U, and G pairs with C.
Verified step by step guidance1
Recall that Watson-Crick base pairing refers to the specific hydrogen bonding between nitrogenous bases in double-stranded DNA.
Identify the four bases in DNA: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).
Understand that Adenine (A) pairs specifically with Thymine (T) through two hydrogen bonds.
Recognize that Guanine (G) pairs specifically with Cytosine (C) through three hydrogen bonds.
Use this knowledge to evaluate the options and determine which correctly describes the base pairing rules in double-stranded DNA.
