Answer:Dna template- 5' ACTCCTGAA 3'

3' TGAGGACTT 5' complementary base

Explanation: Dna consist of a double stranded helix structure. Replication occurs to make extra copies of DNA strand. The DNA strand use to make extra copy is the template strand while the mirror image is the complementary base.

Replication occurs in 5' to 3' direction.

For complementary base in DNA Adenine complement thyamine

Cytosine complement Guanine

i.e A-T

C-G

Hence the complementary base in 3'-5' direction is 3' TGAGGACTT 5'
