Is Different from Other Members of : Monoploidy, Overlapping Replication Cycle, and Unique Segregation Pattern.

Among actinomycetes, chromosome organization and segregation studies have been limited to , , and spp. There are differences with respect to ploidy and chromosome organization pattern in these bacteria. Here, we report on chromosome replication, organization, and segregation in PR4, which has a circular genome of 6.

Ultrasonic study on binary liquid mixtures between some bromoalkanes and hydrocarbons.

Densities and ultrasound velocities for the binary mixtures of 1-bromobutane+benzene and 1,4-dimethylbenzene and of 1-bromopentane+cyclohexane and benzene have been measured at 308.15 K. Adiabatic compressibilities (beta(ad)), and Wada's constants (W) have also been evaluated as a function of composition.
