THROUGHOUT plants and animals the cell nucleus has a uniformity of structure corresponding to the uniformity of its work. This structure has to reconcile the mechanical requirements of cell ...

The last few years have provided us with a new level of understanding of how chromosomes are replicated, segregated and read - and how their 3D organisation influences expression of individual genes ...

Chromosomes ... do not belong to genes. They help regulate the expression of nearby genes. Scientists assign the letters A, T, C, and G to “bases,” which are part of the structure of DNA.

Here's what you should know about genes and longevity, and where genetics fits in among the various theories of aging. The genetic theory of aging states that lifespan is largely determined by the ...

LOY happens due to cell division mistakes, causing the Y chromosome to break apart or be lost. The Y chromosome's unique structure and ... of which are involved in DNA repair and cell cycle ...

Human Y-chromosomal haplogroups are an important tool used in population genetics and forensic genetics ... was performed using ABI PRISM® Data Collection software, while the final Y-STR DNA profiles ...

The cover features a confocal microscopy image of a Drosophila egg chamber showing severe multinucleation in epithelial tissue caused by dystrophin mutation in cells sensitised to cytokinesis failure.

Chromatin is the structure that packages DNA. When it is tightly packed, genes are inactive. When it unpacks, genes can become active again. "Hmga1 clears the way, so to say, allowing dormant ...

Finally we incubated the sample at 37 °C for 16 h and extracted DNA thereafter by standard precipitation techniques. For Southern-blot analysis, we digested isolated chromosomal DNA (2–3 μg ...

2014). Different levels of DNA organization and chromatin packing in the eukaryotic cell’s nucleus are points of application for the epigenetic regulation. Epigenetic mechanisms regulate chromatin ...
