The DNA molecules from T7 bacteriophage and a recently obtained mutant form of T4D were studied. The DNA of this T4 mutant contains cytosine in place of all of the glucosylated hydroxymethylcytosines normally present in T4. Molecular weights were mea

Mutants of bacteriophage T4D that are defective in genes 42 (dCMP hydroxymethylase), 46 (DNA exonuclease), and 56 (dCTPase) produce limited amounts of phage DNA in Escherichia coli B. In this DNA, glucoylated 5-hydroxymethylcytosine is completely rep

We constructed genetic recombinational maps of genes 46 and 47 by using five amber mutants in gene 46, nine amber mutants in gene 47, and two-factor crosses. Two different amber fragments in gene 46 and three different amber fragments in gene 47 were

Proteins labeled with 14C-amino acids after infection of Escherichia coli B by T4 phage were examined by electrophoresis in the presence of sodium dodecyl sulfate. Four regA mutants (regA1, regA8, regA11, and regA15) failed to make a protein having a

Optical diffraction and spatial filtering methods have been used to determine the characteristics of periodic structures in many biological materials. The head shell of bacteriophage T4 has been chosen for this study, since aberrations in the assembl

Mutations termed das were isolated originally (Hercules and Wiberg, 1971) as partial suppressors of mutants in phage T4 genes 46 and 47. Since mutants in genes 46, 47, and 59 exhibit both an early arrest of phage DNA synthesis and the loss of this ar

Cold centrifugation of lysis-inhibited Escherichia coli B infected with wild-type T4D results in extensive lysis beginning around 20 min after infection at 37 degrees C. Infection with an e mutant, which fails to make lysozyme, prevents lysis, but do

Lethal, amber mutations in T4 genes 46 and 47 cause incomplete degradation of host DNA, premature arrest of phage DNA synthesis, accumulation of abnormal DNA replication intermediates, and defective recombination. These phenotypes can be explained by
