Answer: 5' TTGGCTCACCT 3'

Explanation:

The two DNA strands are antiparallel, meaning that if the template strand goes from the 3' end to the 5' end, then the complementary strand will be from the 5' end to the 3'end.

During DNA replication, DNA polymerase adds nucleotides according to the base pairing rules:

  • A ----- T
  • G ----- C

Therefore, according to this understanding, the given strand:

3' AACCGAGTGGA 5'

Matches with the following

Hope this helps!! :)
