Given is the base sequence of a primer used in the polymerase chain reaction.ATGACAAATCGThe base sequence of a DNA fragment to which this primer would bind is
Correct answer: C. TACTGTTTAGC
- A. UACTGUUUAGC
- B. TUCTGTTTAGC
- C. TACTGTTTAGC
- D. UACUGUUUAGC
Explanation
The sequence provided is a DNA primer, which means it is composed of DNA bases: adenine (A), thymine (T), cytosine (C), and guanine (G). DNA does not contain uracil (U), which is found in RNA. The correct complementary base pairing for the sequence ATGACAAATCG would be TACTGTTTAGC, where adenine pairs with thymine, and cytosine pairs with guanine. Therefore, the correct answer is Option C. Options A, B, and D incorrectly use uracil, which is not present in DNA.
