Kaelin Rapport - Histological Techniques for the Sex Determination of Skeletonized Human Remains [PDF]

, 2014
Determining the sex of skeletons is problematic in forensic and bio-archaeological research. Past studies demonstrate that bone cells can sometimes contain preserved sex chromosomal material in ancient samples. The sex chromosomes in skeletal remains may

Bacterial chromosome segregation.

Acta Biochimica Polonica, 2005
In most bacteria two vital processes of the cell cycle: DNA replication and chromosome segregation overlap temporally. The action of replication machinery in a fixed location in the cell leads to the duplication of oriC regions, their rapid separation to the opposite halves of the cell and the duplicated chromosomes gradually moving to the same ...

Survivin and Aurora Kinase A control cell fate decisions during mitosis

Molecular Oncology, EarlyView.
Aurora A interacts with survivin during mitosis and regulates its centromeric role. Loss of Aurora A activity mislocalises survivin, the CPC and BubR1, leading to disruption of the spindle checkpoint and triggering premature mitotic exit, which we refer to as ‘mitotic slippage’.

Periodic Variation of Mutation Rates in Bacterial Genomes Associated with Replication Timing

mBio, 2018
The causes and consequences of spatiotemporal variation in mutation rates remain to be explored in nearly all organisms. Here we examine relationships between local mutation rates and replication timing in three bacterial species whose genomes have ...

Bacterial Chromosome Organization and Segregation [PDF]

Annual Review of Cell and Developmental Biology, 2015
If fully stretched out, a typical bacterial chromosome would be nearly 1 mm long, approximately 1,000 times the length of a cell. Not only must cells massively compact their genetic material, but they must also organize their DNA in a manner that is compatible with a range of cellular processes, including DNA replication, DNA repair, homologous ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Wavelet to predict bacterial ori and ter: a tendency towards a physical balance

BMC Genomics, 2003
Background Chromosomal DNA replication in bacteria starts at the origin (ori) and the two replicores propagate in opposite directions up to the terminus (ter) region. We hypothesize that the two replicores need to reach ter at the same time to maintain a

Fluorescence in situ hybridization in sugarcane or fish-ing in the genomic wilderness. [MO06] [PDF]

, 2015
Cytogenetics applied to sugarcane has brought our fundamental understanding of the sugarcane genome to a new level. In the mid-nineties, Genomic in situ Hybridisation (GISH) was first applied to sugarcane to determine the specific composition of the ...

Spectral Analysis of Guanine and Cytosine Fluctuations of Mouse Genomic DNA

, 2004
We study global fluctuations of the guanine and cytosine base content (GC%) in mouse genomic DNA using spectral analyses. Power spectra S(f) of GC% fluctuations in all nineteen autosomal and two sex chromosomes are observed to have the universal ...
