Do bacteria age? Biologists discover the answer follows simple economics
When a bacterial cell divides into two daughter cells and those two cells divide into four more daughters, then 8, then 16 and so on, the result, biologists have long assumed, is an eternally youthful population of bacteria. ...

Researchers reshape basic understanding of cell division
By tracking the flow of information in a cell preparing to split, Johns Hopkins scientists have identified a protein mechanism that coordinates and regulates the dynamics of shape change necessary for division of a single ...

Slicing mitotic spindle with lasers, nanosurgeons unravel old pole-to-pole theory
The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to researchers at the Harvard School of Engineering ...

Prion proteins play powerful role in survival, evolution of wild yeast strains
Prions, the much-maligned proteins most commonly known for causing "mad cow" disease, are commonly used in yeast to produce beneficial traits in the wild. Moreover, such traits can be passed on to subsequent generations and ...

How old yeast cells send off their daughter cells without the baggage of old age
The accumulation of damaged protein is a hallmark of aging that not even the humble baker's yeast can escape. Yet, aged yeast cells spawn off youthful daughter cells without any of the telltale protein clumps. ...

Chromosome centromeres are inherited epigenetically
Centromeres are specialised regions of the genome, which can be identified under the microscope as the primary constriction in X-shaped chromosomes. The cell skeleton, which distributes the chromosomes to ...

Research team clarifies mechanics of first new cell cycle to be described in more than 20 years
An international team of researchers led by investigators in the U.S. and Germany has shed light on the inner workings of the endocycle, a common cell cycle that fuels growth in plants, animals and some human tissues and ...

Study reveals new role for RNA interference during chromosomal replication
At the same time that a cell's DNA gets duplicated, a third of it gets super-compacted into repetitive clumps called heterochromatin. This dense packing serves to repress or "silence" the DNA sequences within -- which could ...

How bookmarking genes pre-cell division hastens their subsequent reactivation
In order for cells of different types to maintain their identities even after repeated rounds of cell division, each cell must "remember" which genes were active before division and pass along that memory to its daughter ...

The machinery for recombination is part of the chromosome structure
During the development of gametes, such as egg and sperm cells in humans, chromosomes are broken and rearranged at many positions. Using state of the art technology, the research group of Franz Klein, professor for genetics ...

New tasks attributed to Aurora proteins in cell division
(PhysOrg.com) -- When a cell divides, the genetic information in the chromosomes must be passed on error-free to the daughter cells. Researchers at the Friedrich Miescher Laboratory in Tübingen are studying ...
