Inactivation and unstabilization of the transforming principle by mutagenic agents.

In the previous communication (Zamenhof et al., 1953) the study of the inactivation of the transforming principle (deoxyribonucleic acid [DNA] having transforming activity) by several physical and chemical agents has been reported. Some of those agents, especially Fe-++, are known to be potent mutagens; others such as temperature oscillation are reported to be weak mutagens, but they have not b...

Differential stabilities of individual heredity determinants in transforming principle.

Density differences between genetic markers in Pneumococcal transforming principle.

It is known that DNA carries genetic information, and it is commonly assumed that the identity and linear order of the genes are determined by the linear sequence of nucleotides in DNA. However, little is known about the detailed relationship (or "code") between the DNA and proteins of a given species. A linkage group of genes may correspond to a unique nucleotide sequence, or it is possible th...
