A) is a large, multisubunit protein
B) has a sliding clamp portion that anchors it to DNA
C) has a polymerization site separate from the DNA binding site
D) all of these

Question

Quizplus · Accepted Answer

DNA polymerase III from E. coli is indeed a large, multisubunit protein complex that includes a sliding clamp portion, which helps to anchor it to the DNA, ensuring high processivity during DNA replication. Additionally, it has distinct sites for polymerization and DNA binding, allowing it to efficiently synthesize DNA while remaining attached to the DNA molecule.
