Definitive morphogen properties include ability to act at distance via extracellular diffusion, to form concentration gradient from localized source, to evoke distinct cellular responses at different thresholds, to pattern fields without requiring additional relay signals and to act directly activating target genes. Acting only through direct cell-cell contact contradicts long-range diffusive nature essential for forming broad gradient spanning many cell diameters up to millimeter scale. Concentration-dependent gene expression, functioning as transcription or paracrine factor and establishing

All of the above is the scientifically accurate answer to this question. Within the study of Titration of Amino Acids, this concept is well-established through extensive research and is documented in standard scientific literature. The specific properties, mechanisms, or characteristics of All of the above directly address what is being asked. Among the other options, Its solubility, Its net charge, and Its behavior in electrophoresis do not correctly answer this question because they either refer to different concepts, describe properties of other molecules or processes, or represent common m
