Abstract
Continuous cellular incorporation of choline molecules is essential for DNA binding to competent pneumococci. The choline molecules are incorporated into the cell surface at the equatorial region of the cocci. As a working hypothesis, it is proposed that DNA molecules enter these bacteria at the growing zone(s) of the cell envelope.
