Answer:
The best answer to the question: If every gene has a tissue-specific and signal-dependent transcription pattern, how can such a small number of transcriptional regulatory proteins generate a much larger set of transcriptional patterns? Would be:
Because transcriptional regulators, which are the ones responsible for initiating, and stopping, transcription of RNA into protein, often work in pairs, one goes with the other, and thus increase the regulatory capabilities over gene expression so that the genes translated into RNA and then transcribed into aminoacids in protein chains, actually code for the correct protein types.
These regulators will both stand, as appropriate, on a specific gene to promote its transcription, or prevent it, depending on the different signaling mechanisms received.
Explanation:
Planarians are a group of Turbellaria, free-living flatworms that capture their food via a process of wrapping around it, entangling it in slime, and pinning it down before a prey into a gastrovascu lar cavity where free-living flatworms that capture extends from the mouth, bringing the prey into a gastrovascular cavity where free-living flatworms that capture extends from the mouth, bringing the digestion occurs.

Cell sap is the liquid contained within a plant cell vacuole.<span> The chemical composition of this liquid differs significantly from the materials contained outside the vacuole in the surrounding cytosol. This difference aids in the transfer of materials across the vacuole's membrane, called the tonoplast.</span>
