Episome-like behaviour of donor DNA in transformed strains of Neurospora crassa
TRANSFORMATION is a well established process for the transfer of genetic information in bacteria1,2. Although such a system in higher organisms remains to be fully elucidated, certain features of gene transfer in...

Galactosyltransferase of Neurospora
An enzyme, galactosyltransferase, able to catalyze the formation of galactose polymers was detected in cell-free extracts of a wild type strain of Neurospora crassa. Enzyme activity was found in both the super...

Genetic evidence that aphidicolin inhibits in vivo DNA synthesis in Chinese hamster ovary cells
Using a genetic approach, Chinese hamster ovary (CHO) cells sensitive (aphS) and resistant (aphR) to aphidicolin were grown in the presence or absence of various DNA polymerase inhibitors, and the newly synthesiz...
