The function of the beta subunit is to prevent DNA polymerase III from dissociating from the template DNA strand while still allowing the polymerase to slide along DNA as replication progresses. Given this function, the alpha helices in the beta subunit are The function of the beta subunit is to prevent DNA polymerase III from dissociating from the template DNA strand while still allowing the polymerase to slide along DNA as replication progresses. Given this function, the alpha helices in the beta subunit are: a. located on the inner surface and oriented perpendicular to the minor and major grooves of DNA.
b. located on the inner surface and oriented parallel to the minor and major grooves of DNA.
c. located on the outer surface and do not interact with DNA.
