Wildtype phage T4 can grow on the E. coli strain(s) Blank. The rII mutants of T4 can grow on the E. coli strain(s) Blank. This means that rII mutants display distinct Blank properties. Further, the rII mutants of T4 lyse bacteria Blank and, thus, give rise to Blank than their wildtype counterparts. These distinct phenotypes associated with rII mutants allow for the differentiation of r wildtype phages and rII phages.

Respuesta :

Wild-type phage T4 can grow on the E. coli strains B and K12. The rII mutants of T4 can grow on the E.coli strains(s) more rapidly. This indicates that rII mutants have unique host range characteristics. Further, the rII mutants of T4 lyse bacteria more slowly and, thus, give rise to smaller plaques than their wild-type counterparts. These distinct phenotypes associated with rII mutants allow for the differentiation of r + wildtype phages and rII phages.

Defined T4 phages.

Bacteriophage T4 includes a contractile tail, it is categorized as a member of the Caudovirales order's Myoviridae family. Before being combined to form a mature phase, T4's head, tail, and long tail fibers (LTFs) are built separately.
