THE findings that the thermal denaturation temperature (Tm) of DNA from a wide variety of bacterial, plant and animal sources as well as the buoyant density in a cæsium chloride gradient are linearly related to the guanine plus cytosine (G plus C) base composition1–2 have made it possible to search for the existence of DNA samples which would show an anomalous behaviour with respect to these two parameters. Native DNA preparations which show no correlation between their buoyant density and Tm… 

2-Aminoadenine is an adenine substituting for a base in S-2L cyanophage DNA

TLDR
The isolation and identification of the base 2-aminoadenine and its deoxyribonucleoside from S-2L cyanophage DNA is reported and some unusual properties of this DNA in which adenine is completely substituted with 2-AMB are described.

DNase Specific for Uracil-Containing Bacteriophage DNA

TLDR
A DNase from Bacillus subtilis which specifically hydrolyzes native DNA of phage PBS 1 has been purified and characterized and yielded deoxyuridine and oliogonucleotides of various sizes.

DNA glycosylases, endonucleases for apurinic/apyrimidinic sites, and base excision-repair.

New Deoxyribonucleic Acid Polymerase Induced by Bacillus subtilis Bacteriophage PBS2

TLDR
The deoxyribonucleic acid of Bacillus subtilis phage PBS2 has been confirmed to contain uracil instead of thymine, and this phage-induced polymerase may be responsible for the synthesis of Uracil-containing DNA during PBS2 phage infection.

Synthesis of the Unusual DNA of Bacillus subtilis Bacteriophage SP-15

TLDR
Analysis of the bases from hydrolyzed DNA of labeled phage or infected cells indicated that the uracil was incorporated into the DNA as such (presumably via deoxyuridine triphosphate) and later converted to DHPU and thymine at the macromolecular level.
