Multiple Choice
Which DNA base pairs with cytosine during the process of independent assortment?
A
Uracil
B
Guanine
C
Thymine
D
Adenine
Verified step by step guidance1
Recall the base pairing rules in DNA, which state that cytosine (C) pairs with guanine (G) through three hydrogen bonds.
Understand that during DNA replication and independent assortment, the complementary base pairing ensures accurate copying of genetic information.
Identify that uracil (U) is found in RNA, not DNA, so it does not pair with cytosine in DNA.
Recognize that thymine (T) pairs with adenine (A), not cytosine.
Conclude that guanine (G) is the correct base that pairs with cytosine (C) in DNA.
