Figure 1 Negative contrast electron micrograph of Acholeplasma phage L2 (L2) virions. The pleomorphic virion appears as a core (perhaps a nucleoprotein condensation) within a baggy membrane. The bar represents 100  nm. (From Poddar, Cadden, Das and Maniloff, 1985. With permission.)

Figure 2 Map of genome organization of Acholeplasma phage L2 (L2), showing ORFs as determined from analysis of the 11,965  bp sequence. The base on the 3-side of the single BstE II cleavage site is taken as the first base on the DNA sequence. The map also shows locations of the Acholeplasma phage L2 integration site (attp) and the two Acholeplasma phage L2 DNA replication origin sites (ori1 and ori2).
