Inter-chromosomal k-mer distances

BMC Genomics, 2021
Background Inversion Symmetry is a generalization of the second Chargaff rule, stating that the count of a string of k nucleotides on a single chromosomal strand equals the count of its inverse (reverse-complement) k-mer.

Bacterial chromosome segregation

Frontiers in Bioscience, 2012
Dividing cells have mechanisms to ensure that their genomes are faithfully segregated into daughter cells. In bacteria, the description of these mechanisms has been considerably improved in the recent years. This review focuses on the different aspects of bacterial chromosome segregation that can be understood thanks to the studies performed with model

Systematic determination of the mosaic structure of bacterial genomes: species backbone versus strain-specific loops [PDF]

, 2005
Background Public databases now contain multitude of complete bacterial genomes, including several genomes of the same species. The available data offers new opportunities to address questions about bacterial genome evolution, a task that requires ...

SMC is recruited to oriC by ParB and promotes chromosome segregation in Streptococcus pneumoniae [PDF]

, 2011
Segregation of replicated chromosomes is an essential process in all organisms. How bacteria, such as the oval-shaped human pathogen Streptococcus pneumoniae, efficiently segregate their chromosomes is poorly understood.

Bacterial chromosome segregation [PDF]

Microbiology, 2001
Recent years have witnessed a resurgence of interest in how the bacterial chromosome is organized and how newly replicated chromosomes are faithfully segregated into daughter cells on cell division. In the past, the problem with studying bacterial chromosomes was their lack of any obvious morphology, combined with the lack of ability to readily ...

Annotated bacterial chromosomes from frame-shift-corrected long-read metagenomic data

Microbiome, 2019
Background Short-read sequencing technologies have long been the work-horse of microbiome analysis. Continuing technological advances are making the application of long-read sequencing to metagenomic samples increasingly feasible.

Contrasting roles of condensin I and condensin II in mitotic chromosome formation [PDF]

, 2012
© 2012. Published by The Company of Biologists LtdIn vertebrates, two condensin complexes exist, condensin I and condensin II, which have differing but unresolved roles in organizing mitotic chromosomes.

Organization and segregation of bacterial chromosomes [PDF]

Nature Reviews Genetics, 2013
The bacterial chromosome must be compacted more than 1,000-fold to fit into the compartment in which it resides. How it is condensed, organized and ultimately segregated has been a puzzle for over half a century. Recent advances in live-cell imaging and genome-scale analyses have led to new insights into these problems. We argue that the key feature of
