What Controls the Cell Cycle Although the recursive events leading to the birth of new cells are well known, biologists are only now learning how those events are regulated. One protein is the major regulator in
Cell Cycle: What Controls Division?doi:10.1038/newbio229163a0NoneNature New Biology
What is the organelle that holds the cell's DNA and controls cell activities? What is the cell wall's function in the cell? What characteristics of the cell membrane determine what gets into the cell and what doesn't? What problems do you think a cell would have if it could not control...

WUS is expressed in OC cells, and it changes the cell fate non-cell-autonomously and activates the expression of CLV3 by moving from the OC to the CZ. In return, CLV3 can repress WUS expression. This feedback regulation controls the cell number and cell niche size of SAM, and is ...
What controls what enters and leaves the cell? What is the G0 phase of the cell cycle? Which factors determine whether a cell enters G0? Can cells leave G0? What are the roles of cyclins, and (de)phosphorylated CdKs in the cell cycle control system?

Metal-oxide-semiconductor field-effect transistors, also known asMOSFETor MOS semiconductor memory, was invented in 1959. This enabled the use of MOS transistors as elements for memory cell storage. MOS memory was cheaper and needed less power compared to magnetic-core memory. Bipolar memory, which...
Such cases certainly do exist: for example, in the case of viral infections in which a certain protease is required for replication or a receptor is required for cell entry. Also, target-based drug discovery has led to a significant number of approved drugs, and in particular to follow-up ...
