For replication of a single strand DNA sequence tac taa gca which of the following enzymes proofread and add complementary nucleotides to the new DNA strand ?

DNA polymerase

Explanation:

During replication which involved the duplication of the DNA helix, the replication machinery which includes helicases, topoisomerases, single strand binding proteins, DNA polymerase, DNA primase, ligases etc are involved in the synthesis of the new DNA strands. Each of these enzymes play different role in the process. The DNA polymerase performs the functions of proofreading (checking for the incorporation of the correct nucleotide) and also functions in addition of complementary nucleotides to the new DNA strand.
