Models of packaged T4 DNA structure. (a) T4 DNA is packed longitudinally to the head–tail axis (Earnshaw et al., 1978), unlike the transverse packaging in T7 capsids (Cerritelli et al., 1997) (b). Other models shown include spiral fold (c), liquid crystal (d), and icosahedral bend (e). Both packaged T4 DNA ends are located in the portal (Ray et al., 2010a). For references and evidence bearing on packaged models see (Mullaney and Black, 1998).
