Advanced Placement (AP) Biology (also known as AP Bio) is an Advanced Placement biology course and exam offered by the College Board in the United States. For the 2012–2013 school year, the College Board unveiled a new curriculum with a greater focus on "scientific practices".
In Windows 7 and later, significant hardware changes (e.g. motherboard) may require a re-activation. In Windows 10 and 11, a user can run the Activation Troubleshooter if the user has changed hardware on their device recently. If the hardware has changed again after activation, they must wait 30 days before running the troubleshooter again.
Bcl-2 derives its name from B-cell lymphoma 2, as it is the second member of a range of proteins initially described in chromosomal translocations involving chromosomes 14 and 18 in follicular lymphomas. Orthologs [9] (such as Bcl2 in mice) have been identified in numerous mammals for which complete genome data are available.
[2] [3] [4] The activity of activators is controlled by the ability of the activator to bind to its regulatory site along the DNA. [2] [3] [4] The DNA-binding domain of the activator has an active form and an inactive form, which are controlled by the binding of molecules known as allosteric effectors to the allosteric site of the activator.

One can think of molecular docking as a problem of “lock-and-key”, in which one wants to find the correct relative orientation of the “key” which will open up the “lock” (where on the surface of the lock is the key hole, which direction to turn the key after it is inserted, etc.). Here, the protein can be thought of as the “lock ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Ca 2+ /calmodulin-dependent protein kinase II (CaM kinase II or CaMKII) is a serine/threonine-specific protein kinase that is regulated by the Ca 2+ /calmodulin complex. CaMKII is involved in many signaling cascades and is thought to be an important mediator of learning and memory. [1] CaMKII is also necessary for Ca 2+
Steps of the cell cycle. The restriction point occurs between the G 1 and S phases of interphase.. The restriction point (R), also known as the Start or G 1 /S checkpoint, is a cell cycle checkpoint in the G 1 phase of the animal cell cycle at which the cell becomes "committed" to the cell cycle, and after which extracellular signals are no longer required to stimulate proliferation.
