Chromosomal mapping of the stf region. An internal fragment of stfC was hybridized to an ordered array of Mud-P22 mapping phages which individually package defined genomic segments (7). The signals obtained are correlated with the chromosomal start point (o) of DNA packaging, and the direction of DNA packaging of individual phages is indicated.
