Biochem Soc Trans (2019) 47 (3): 839–845.
Published: 12 June 2019
.... Here, we review recent data indicating that the activity of the Escherichia coli lac operon promoter also depends upon its chromosomal location. Factors that affect promoter activity include the binding of nucleoid-associated proteins to neighbouring sequences, supercoiling and the activity...

...Susan L. Forsburg Replication stress is a significant contributor to genome instability. Recent studies suggest that the centromere is particularly susceptible to replication stress and prone to rearrangements and genome damage, as well as chromosome loss. This effect is enhanced by loss...

...Hiroshi Sato; Shigeaki Saitoh The kinetochore, which forms on a specific chromosomal locus called the centromere, mediates interactions between the chromosome and the spindle during mitosis and meiosis. Abnormal chromosome rearrangements and/or neocentromere formation can cause the presence...

...Geert J.P.L. Kops Error-free chromosome segregation during cell division relies on chromosome biorientation and mitotic checkpoint activity. A group of unrelated kinases controls various aspects of both processes. The present short review outlines our current understanding of the roles...

...Dan Liu; Michael A. Lampson Accurate segregation of chromosomes in mitosis requires that spindle microtubules attach sister kinetochores to opposite poles of the mitotic spindle (biorientation). To achieve biorientation of all chromosomes, incorrect attachments are selectively destabilized...

...A. Zalensky; I. Zalenskaya Elaborate non-random organization of human sperm chromosomes at different structural levels, starting from the DNA packing by protamines up to the higher-order chromosome configuration and nuclear positioning of chromosome territories, has been discovered.

...C. Mézard Many studies have demonstrated that the distribution of meiotic crossover events along chromosomes is non-random in plants and other species with sexual reproduction. Large differences in recombination frequencies appear at several scales. On a large scale, regions of high and low rates...
