The Nucleic Acids of T2, T4, and T6 Bacteriophages
The deoxyribonucleic acids of the wild type strains of the T(2), T(4), and T(6) bacteriophages have been shown to contain glucose as an integral part of the molecule; the amount of hexose present in each nucleic acid differs. A study of the acid degradation products of the three nucleic acids has revealed that in each instance glucose is linked to the apurinic acid component. In the case of the...
متن کاملNucleotides derived from enzymatic digests of nucleic acids of T2, T4, and T6 bacteriophages.
The compositions of the nucleic acids of the T even bacteriophages, T2, T4, and T6 have been shown to be identical with respect to their purine and pyrimidine bases within the accuracy of existing analytical methods for these bases (1). However these viruses contain the unusual pyrimidine, 5-hydroxymethyl cytosine, which provides a unique opportunity for chemical variability in the composition ...
متن کاملInterrupted thymidylate synthase gene of bacteriophages T2 and T6 and other potential self-splicing introns in the T-even bacteriophages.
Southern hybridization analyses of procaryotic DNA from Escherichia coli, lambda bacteriophage, and T1 to T7 phages were carried out. The hybridization probes used consisted of DNA restriction fragments derived from the T4 phage intron-containing thymidylate synthase gene (td) and short synthetic oligodeoxynucleotides defining specific exon and intron regions of the gene. It was shown that inta...
متن کاملThe Inheritance of the Protein and Nucleic Acid Characteristics of T2 and T6 Bacteriophage
A study of the immunological properties of phage strains derived from T2 x T6 crosses revealed that the majority of the progeny differ serologically from the parental viruses. Some hybrids were found to contain head membranes having the serological specificity of both T2 and T6 phages, while others contained tail sheaths of the former and the tail fibers of the latter. Since the immunological p...
متن کاملEffect of prophage W on the propagation of bacteriophages T2 and T4.
Studies have been undertaken to determine whether the temperate phage omega present in Escherichia coli strain W is responsible for the inability of this strain to act as a host for T2 and T4. E. coli WS, cured of phage omega, was sensitive to T2 and T4. Lysogenation of E. coli C and WS with phage omega resulted in loss of ability to plate T2 and T4. However, E. coli K-12 lysogens still served ...
