In DNA, cytosine always paired with _______*1 pointOption 5adenineThyminecytosineguanine

Break Down the Problem

1. Identify the nature of DNA base pairing.
2. Recognize which base pairs with cytosine.

Relevant Concepts

• In DNA, the bases pair specifically: adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Analysis and Detail

Cytosine (C) is one of the four main bases found in DNA. Its complementary base is guanine (G). Each base pairs in a specific manner to maintain the structure of the DNA double helix.

Verify and Summarize

To verify, recall the base pairing rules:

• A pairs with T
• C pairs with G

Final Answer

Cytosine always pairs with guanine.
