The phrase "activity of the specification" is correct and usable in written English.
It can be used in contexts related to project management, technical documentation, or any situation where specifications are being discussed in relation to their implementation or execution.
Example: "The activity of the specification must be clearly defined to ensure all team members understand their roles."
Alternatives: "function of the specification" or "process of the specification".
Localized to either an individual cell or group of cells, embryonic organizing activity induces the specification of other cells in the embryo and can influence formation of body axes.
The definition of activity cliffs requires the specification of a similarity criterion (when are two compounds "similar"?) and a potency difference criterion (when is a potency difference "large" and "significant"?).
Therefore, we addressed whether FGF signals act together with BMP activity during the specification of neural retina cells.
Hh pathway activity underlies the specification of distinct muscle cell types in the zebrafish embryo, in part through the activation of the engrailed2 (engenegene in subsets of slow-twitch and fast-twitch myoblasts (Wolff et al., 2003).
Dpp is essential for BMP activity and controls the specification of all tissues that develop under the control of this pathway in the early embryo, including amnioserosa and dorsal ectoderm [ 16, 29].
Our results suggest an interplay between Act and Wnt/β-catenin signalling, the EMT and the activity of Bra in the specification and behaviour of cells in the primitive streak.
Although parallel with respect to specification from a proneural fate equivalence group, the pPIm NE requires activity of the AS-C for IPC NB specification whereas Ato is not essential (data not shown).
Hence, there is a need for approaches to guide the designers to perform activities related to the specification of the behavior of context-sensitive systems.
The pluripotent condition may thus be viewed as a transcription factor battlefield in which Oct4, Sox2, and Nanog are dominant and continuously suppress functional expression and activity of lineage specification factors (Niwa, 2007; Smith, 2005) Crucially, however, Oct4 and Sox2 also provide for developmental extinction of pluripotency by directing expression of FGF4.
The second phase of the specification process mainly consisted of activities that dealt with specific client situations.
