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.
Answer:
Iceland, and states like Washington DC.
, South Dakota, Connecticut, Idaho, New Hampshire, Delaware, North Dakota, Illinois.
Explanation:
Iceland is one of the only places where people live without insects.
The reason why Iceland does not have mosquitos or other insects is its oceanic climate that keeps them away.
The insects freeze 3 times a year, which makes their survival in Iceland impossible.
The other states are not completely insect-free, however, their number is so small that is considered as like they don't exist.
