It takes the time that it takes.
It was five days before my first Christmas in Perth, Australia, and our family had begun to arrive the night before.

Though I feared I would be late, I could see people mil...

control may kick in even before a kinetochore is assembled. The mitotic checkpoint— controlled by Mad1, Mad2, Bub1, BubR1, and Bub3— delays anaphase by inhibiting APC until all kinetochores are properly attached to the spindle. Because inhibition of Mad2 leads to an accelerated mitosis and a precocious anaphase, it has been assumed that the checkpoint itself also regulates mitotic timing. But M...

T he mechanism of movement of individual cells shows extensive diversity. In the Eukarya, ATP is the driving force for cell motility (1). In contrast, in the Bacteria and Archaea, the chemiosmotic pathway of energy transduction powers flagellar rotation. Depending on the species, either hydrogen or sodium ion flux results in cell movement. ATP does not directly participate in providing the ener...
متن کاملSplicing takes a NAP
plicing factors, usually associated with RNA polymerase II transcripts, have a temporary home near sites of RNA polymerase I transcription, as shown on page 51 by Bubulya et al. During interphase, premRNA splicing factors such as the serine arginine–rich (SR) proteins reside in nuclear speckles, along with other pre-mRNA processing proteins. The speckles disassemble during mitosis, and then ref...

Especially when it is added onto preexisting polypharmacy in older adults, iron can subject patients to a plethora of dose-related side effects and drug interactions. Judicious use of laboratory st...
