The alpha helices in the beta subunit are a ring shaped protein.
Explanation:
<em>Because the beta encircles DNA like a ring used gel filtration and radioactive beta subunit. Tipically beta and gamma complex are needed for fast and processive synthesis by polymerase III core. Some researchers realized that adding polymerase III core to the gel filtered isolated ³H-beta- DNA provide fast DNA synthesis typical of the polymerase III holoenzyme. Therefore the gamma complex is only needed to get the beta subunit onto the DNA, and is not required afterward.</em>
A resistor is a electrical component that implements electrical resistance as a circuit element. They are used to reduce circuit flows, adjust circuit level and divide voltages.
