||Primary source abstract: "[Investigators] have analyzed the kinetics of the K+ efflux induced by T4 phage and ghosts (phage depleted of DNA) using a potassium selective electrode."
||P.726 right column: "T4, for example, attaches to the cell surface via fibers that are attached to a baseplate at the tip of the tail. Upon successful adsorption, conformational changes in
the baseplate trigger contraction of a tail sheath, which then drives the tail tube through the cell envelope [ref 1]. T4 transports a 169-kbp genome into the
cell cytoplasm in 30 s. This is one of the most efficient DNA transport processes known [primary source]."
