Prion

... prion form of HET-S spreads rapidly throughout the cellular network of a colony and can convert the non-prion form of the protein to a prion state after compatible colonies have merged. However, when an incompatible colony tries to merge with a prion-containing colony, the prion causes the ...

Alexander Fleming

... sorting through the many idle experiments strewn about his lab. He inspected each specimen before discarding it and noticed an interesting fungal colony had grown as a contaminant on one of the agar plates streaked with the bacterium Staphylococcus aureus . Fleming inspected the Petri dish ...

Antibiotic

... which was ruined by an accidental fungal contamination. Rather than discarding the contaminated plate, Fleming noticed a clear zone surrounding the colony of mold . Having previously studied the ability of the enzyme lysozyme to kill bacteria, Fleming realized that the mold was secreting something ...

Prokaryote

... always unicelluar, some are capable of forming groups of cells called colonies . Unlike many eukaryotic multicellular organisms, each member of the colony is undifferentiated and capable of free-living. Colonies are formed by organisms that remain attached following cell division , sometimes through ...

T cell

... CD4 molecules or CD8 molecules and leave the thymus via postcapillary venules. Hormonal substances (thymosin, interferon γ, interleukins, colony stimulating factors, thymopoetin) secreted by type VI epithelioreticular cells within the thymic (Hassal's) corpuscles promote the process of thymic ...
