Step 1
Which of the following shows correct base pairing in DNA replication?
Answer
In DNA replication, base pairing follows specific rules where adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G).
Analyzing each option:
- Option A: This shows UACACGGU, which is an RNA sequence and not relevant for DNA.
- Option B: Here, GGCA is not paired with correct bases.
- Option C: AATGTGCA is paired correctly with TTA CAC GGT. This shows A-T and G-C pairs, making it a potential candidate.
- Option D: This option contains incorrect pairing as well.
Thus, the correct answer is C: AATGTGCA paired with TTA CAC GGT.
