The type of macromolecule that adds base pairs to the complementary strand during replication is a protein.
Here's why:
1. DNA replication is a complex process where DNA polymerase, a type of protein, adds complementary nucleotides to the newly forming DNA strand.
2. Proteins like DNA polymerase have specific functions in DNA replication, including proofreading the newly synthesized DNA strand to ensure accuracy.
3. These proteins play a crucial role in ensuring that the genetic information is faithfully copied during replication.
Therefore, proteins are essential macromolecules that add base pairs to the complementary strand during DNA replication.
