... of the fly wing. In fact, Notch has a repressor function, that is to say, when it is activated the cell division machinery is arrested. Only when Wnt/Wingless starts to work is Notch silenced, ...
... 's lasso: it catches chromosomes and ties them to a transitory structure assembled during cell division. Once they have been neatly tied up, the chromosomes await the end of replication to be equally ...
... cell division, one of the most fundamental processes in all biology, has been unraveled. Although the steps of cell division are familiar to all pupils studying biology in schools, the details of how ...
... to divide with a backup system that can work if the other approach fails.
"Accurate cell division is one of the most critical of all life functions, and there clearly is an evolutionary value to ...
... Li Lab has characterized a mechanism that allows for asymmetrical cell division during meiosis in oocytes. By tracking ... related to problems during oocyte meiotic cell divisions," said Rong Li, Ph.D., ...
Scientists have characterized a mechanism that allows for asymmetrical cell division during meiosis in oocytes. By tracking chromosome movement in live mouse oocytes, they have discovered that ...
... that two new daughter cells are formed.
- This is the first time in decades that a novel cell division mechanism has been discovered, and the gene products display no similarity to previously known ...
... emerging from the base of the meristem. Thus, the initial growth and shape of leaves is by cell division, and more than 90% of leaf growth is by subsequent cell expansion.
Reporting in the online, ...
Biologists found that when leaves of the model plant Arabidopsis are wounded, cell division in the apical meristem is reduced, growth of the plant is arrested within days, and the new leaves grow to ...
... new targets for drugs to stop cancerous cell division, said Bruce Bowerman, professor of biology ... microfilament structure plays a role in healthy cell division. However, finding that such shape-shifting ...
... is assembled from two protein filament types, actin and myosin, that are also used in muscle. During cell division, the genome is replicated and the two copies are separated to opposite sides of ...
Researchers have identified a key step required for cell division in a study that could help improve therapies to treat cancer. Their work describing the mechanism of the contractile ring -- a ...
... -B-containing spindle matrix, in turn, works with microtubules to orchestrate spindle assembly and cell division.
"Isolating the spindle matrix and identifying its components has also allowed us to ...
... in a cell must reliably convey instructions for such essential processes as DNA replication and cell division.
How big are the molecular fluctuations expected in a single yeast cell? Physicists ...
... , the other self-renews. This fate asymmetry is thought to depend on the orientation of cell division, and the authors observed an increase in the number of symmetrically dividing progenitors in the ...
