TgSUB1 is a microneme protein, whereas TgSUB2 localizes to rhoptries and associates with rhoptry protein ROP1, a potential substrate.
The activity of thinking can be represented as heuristic procedures--trans-frames, micronemes, ways to think, K-lines, Abrains, and B-brains.
Transmission electron microscopy revealed a uniform size, a smooth surface and intact cell or nuclear membranes with an oval-shaped nucleus also conoids and micronemes were observedin control group.
During invasion and creation of the PV membrane, apically oriented organelles called micronemes and rhoptries are discharged, followed later by release of dense granules content (DG).
Some of these include property lists or polynemes, frames and transframes, frame-arrays, database query languages, explanation-based reasoning, haptic representations, K-trees and level-bands, logic programming, rule-based systems, micronemes, natural language expressions, semantic networks, scripts and stories, and object-based programming.
In order to invade the host cell they employ an arsenal of virulence factors derived from the specialised secretory organelles; the micronemes, rhoptries and dense granules that are sequentially secreted during the invasion process.
