To determine the complementary DNA base sequence, we need to understand the pairing rules of DNA bases. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).
The given sequence is TAC.
Using the base pairing rules:
- T pairs with A
- A pairs with T
- C pairs with G
So, the complementary bases to TAC would be:
- T → A
- A → T
- C → G
This means the complementary DNA base sequence in the other strand is ATG.
