Replication of the bacterial chromosome
In this paper I shall confine myself to only one aspect of chromosome replication in bacteria: its control and co-ordination with growth and cell division. The nature of the problem to be considered is made clear by two features of chromosome replication in Escherichia coli, First, under conditions of rapid growth, involving generation times of up to about one hour, DNA synthesis is essentially...
متن کاملThe haloarchaeal chromosome replication machinery.
The powerful combination of genetic and biochemical analysis has provided many key insights into the structure and function of the chromosomal DNA replication machineries of bacterial and eukaryotic cells. In contrast, in the archaea, biochemical studies have dominated, mainly due to the absence of efficient genetic systems for these organisms. This situation is changing, however, and, in this ...
متن کاملChromosome I Controls Chromosome II Replication in Vibrio cholerae
Control of chromosome replication involves a common set of regulators in eukaryotes, whereas bacteria with divided genomes use chromosome-specific regulators. How bacterial chromosomes might communicate for replication is not known. In Vibrio cholerae, which has two chromosomes (chrI and chrII), replication initiation is controlled by DnaA in chrI and by RctB in chrII. DnaA has binding sites at...
متن کاملX-chromosome replication in early rabbit embryos.
is generally believed that the sex chromatin which is found in the cells of 'Lammalian Eemales represents a genetically inactive X chromosome (LYON 1961 ; RUSSELL 1961 ) iwhich is heterochromatic and is replicated out of synchrony with the other X (ATKINS, TAFT and DALAL 1962; GRUMBACH, MORISHIMA and TAYLOR 1963; OHNO and CATTANACH 1962). According to the single-active-X hypothesis, inactivatio...
متن کاملPolarity of chromosome replication in Neisseria meningitidis.
Jyssum, Kaare (University of Oslo, Oslo, Norway). Polarity of chromosome replication in Neisseria meningitidis. J. Bacteriol. 90:1182-1187. 1965.-Relative frequencies of various genetic markers in the deoxyribonucleic acid of Neisseria meningitidis in exponential- and stationary-growth phases were compared by use of a transformation system. On the basis of an analysis of eight genetic markers, ...
