Question

Quizplus · Accepted Answer

As unwinding of the helix occurs during DNA replication, tension referred to as supercoiling is created ahead of the replication fork. This tension is relieved by the action of DNA gyrase, making C the best choice. Single-stranded binding proteins stabilize single-stranded DNA while primase synthesizes RNA primers and processivity refers to the ability of the replicative polymerase to move along the DNA template without dissociating. DNA helicase unwinds the double-stranded DNA.
