1. [A simple and rapid method to test the permeability of condoms to viruses]

Author

D, Beytout, M, Chambon, H, Laveran, C, De Champs, H, Peigue-Lafeuille, and D, Socquet

Subjects
Quality Control, Contraceptive Devices, Male, Humans, T-Phages, Bacteriophage phi X 174, Permeability
Abstract

phi x 174 and T7 coliphages can be used to find out if condoms are virus-proof. Protection against hepatitis B virus or papillomavirus contamination is not assured when T7, a 65 nm broad virus, leaks through the condom. The simple test can be used to establish a quality control norm for condoms.

3. [Use of the degeneracy of the genetic code by selective pressure to cut up genes of procaryote genomes]

Abstract

The DNA sequences of three bacteriophages are analysed in order to localise those parts coding for a protein. A weak stability on the DNA molecule allows us to characterize the beginning and the end of genes. A survey of the codons used shows that the cause for this weak stability is the systematic use of A-T bases in third position, which is made possible by the degeneracy of the genetic code.
