15 Cards in this Set

  • Front
  • Back
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.
