We examined the DNA of Saccharomyces cerevisiae by both Hpa II-Msp I restriction enzyme
digestion and high-performance liquid chromatography analysis for the possible presence of …

This brief paper could in no way cover the available literature in this immense and growing
field. Some general review articles which list many of the original citations are included (1-3 …

In many viral and nonviral eukaryotic systems, an inverse correlation has been observed
between the extent of DNA methylation at 5'-CCGG-3'sites and the extent of expression of …

During the past few decades we have witnessed an era of remarkable growth in the field of
molecular biology. In 1950 very little was known of the chemical constitution of biological …

Nucleotide composition varies greatly among DNA viruses of animals, yet the evolutionary
pressures and biological mechanisms driving these patterns are unclear. One of the most …

RNA plays an important role in biology, and more than 170 RNA modifications have been
identified so far. Post-transcriptional modification of RNA in cells plays a crucial role in the …

Adult White Leghorn chickens were rendered anemic by injection with 1-acetyl-2-
phenylhydrazine and then treated with parenteral 5-azacytidine, and levels of embryonic …

The epidemiology of herpes simplex virus (HSV) infections in man has a number of unusual
features (see Whitley, this volume). In particular, the recurrent lesions (herpes labialis …

Glioma is the most common intracranial malignant tumour. A clear diagnosis and molecular
targeted therapy are of great significance for improving the survival time and quality of life of …

The insertion of adenovirus type 12 (Ad12) DNA into the hamster genome and the
transformation of these cells by Ad12 can lead to marked alterations in the levels of DNA …
