Question

Quizplus · Accepted Answer

Single-stranded DNA binding (SSB) proteins bind selectively to single-stranded DNA and are responsible for keeping it extended and preventing it from being rewound. DNA helicase helps to unwind the double-stranded DNA, and DNA gyrase relieves the tension that builds up ahead of the replication fork by introducing negative supercoils into the DNA molecule. ATPase provides the energy needed for various DNA-related processes, and DNA unwindase is not a known protein.
