Answer:

CAGGTA

Step-by-step explanation:

This is according to the complementary base sequence in DNA.

Just remember that it goes:

A - T (Adenine to thymine)

G - C (Guanine to cytosine)

If you look at the answer all I have done is wrote the corresponding letter for the original base sequence.

Therefore it is, CAGGTA (for this specific sequence).
