If the base sequence of one strand of DNA is CAT. TAG. TAC. GAC, what will be the base sequence of complementary DNA strand?

Explanation

To find the base sequence of the complementary DNA strand, we need to remember the base pairing rules of DNA. In DNA, the bases pair as follows:

- Adenine (A) pairs with Thymine (T)
- Thymine (T) pairs with Adenine (A)
- Cytosine (C) pairs with Guanine (G)
- Guanine (G) pairs with Cytosine (C)

Now, let's apply these rules to the given DNA strand: CAT. TAG. TAC. GAC.
