The helicase and primase make up a protein replication complex called:

Question

Quizplus · Accepted Answer

The helicase and primase together form the primosome, which is responsible for unwinding the double-stranded DNA and synthesizing RNA primers, respectively. Therefore, the best choice is B, the primosome. DNA polymerase is responsible for adding nucleotides to the growing DNA strand, but it does not include the helicase and primase components. DNA replicase is a general term for any enzyme complex involved in DNA replication, but it does not specifically refer to the helicase and primase complex. DNA ligase is responsible for sealing nicks in DNA strands, but it is not involved in unwinding or priming the DNA.
