|
base analogs
|
molecules that resemble normal DNA nucleotides and can substitute for them during DNA replication, leading to mutations.
|
|
|
basic dyes
|
dyes that are cationic, or have positively charged groups, and bind to negatively charged cell structures.
|
|
|
B cell antigen receptor(BCR)
|
a transmembrane immunoglobulin complex on the surface of a B cell that binds an antigen and stimulates the B cell.
|
|
|
benthic
|
pertaining to the bottom of the sea.
|
|
|
beta hemolysis
|
a zone of complete clearing around a bacterial colony growing on blood agar.
|
|
|
beta oxidation pathway
|
The major pathway of fatty acid oxidation to produce NADH, FADH2 and acetyl coenzyme A.
|
|
|
binal symmetry
|
the symmetry of some virus capsids(those of complex phages) that is a combination of icosahedral and helical.
|
|
|
CD95 pathway
|
the CD95 receptor is found on many nucleated eucaryotic cells. When the receptor is bound to a specific ligand(CD95L), the CD95-CD95L complex activates several cytoplasmic proteins that initiate a cellular suicide leading to apoptosis.
|
|
|
Cell cycle
|
The sequence of events in a cells growth division cycle between the end of one cell division and the end of the next. In eucaryotic cells, it is composed of the G1 period, the S period in which DNA and histones are synthesized, the G2 period and the M period(mitosis).
|
|
|
chicken pox
|
caused by varicella zoster virus.
|
|
|
choleragen
|
cholera toxin
|
|
|
classical complement pathway
|
antibody dependent pathway of complement activation.
|
|
|
cluster of differentiation molecules
|
functional cell surface proteins or receptors that are measured in situ from peripheral blood, or fluids. They are used to identify leukocyte subpopulations.
Examples are interleukin 2 receptor, CD4 CD8 and CD25 and intercellular adhesion molecule. |
|
|
coagulase
|
an enzyme that induces blood clotting, it is produced by pathogenic staphylococcus.
|
|
|
complex viruses
|
viruses with capsids having a complex symmetry that is neither icosahedral nor helical.
