The position of the centrosome within the cell is important in such directional activities as wound closure and interactions of immune cells.
Bi-directional activity might be inadequate to be conducted in particular network situation in which down-link bandwidth is much bigger than its up-load bandwidth.
Undoubtedly, this two-directional activity of uric acid, as both potent antioxidant and cardiovascular risk factor, would require further studies [ 45– 45].
LacI cassette such that the TRE has bi-directional activity on both the LacI and tTA genes, and (3) original TRE promoter controlling GFP expression, cloned downstream of the ARR2PB.
Finally, future studies that aim to examine the protective and restorative effects of exercise should test exercise interventions that are specifically designed to have maximal osteogenic effect, i.e., <100 loading cycles per session of high-impact, dynamic, multi-directional activity (Turner and Robling 2005).
It is possible that bi-directional activities exist, or that alternative enzymes take over this conversion (i.e. co-option).
Each of these interactions represents a directional enzymatic activity, where the bait protein executes the activity on the substrate hit protein.
Our studies show clearly that directional flight activity and time-compensated sun compass orientation persist independent of reproductive state; oriented flight activity has also been shown in disappearance bearing studies of reproductively active migrants [ 10], but persistent time-compensation had not been shown previously.
Finally, by injecting inert particles of different sizes, we show that this directional transport activity is size-selective and transduced to chromosomal cargo at least in part by steric trapping or "sieving".
