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:
The STR fragments will have different size for different animals.
Explanation:
- STR means Short Tandem Repeats.
- STR forms the genome's microsatellite region.
- STR or microsatellite is that region of the genome where, about two to seven base pairs of the DNA (for example, ATGATGATGATG), are repeated for multiple time. Such sequences can have few hundred repeats.
- While replicating these micro-satellite regions, the accuracy of the DNA polymerase in proof-reading the sequence of the newly synthesised strand, decreases, due to the multiple repeats.
- As a result of this, the DNA polymerase either adds more or adds less of such repeated sequences as compared to the parental DNA sequence. This results in generation of polymorphism (different microsatellite size in different individuals) in the repeat regions.
- Due to difference in size of the STR in different individuals, the size of the fragment amplified through PCR will vary for different elephants.
The eukaryotic cell contains the nucleus and membrane bound organelles, whereas the prokaryotic cell lacks a membrane bound nucleus and membrane bound organelles. The part where prokaryotes store their genetic information is called the nucleoid. The eukaryotes include the animals, plants, protists and fungi. Hope this answer helps.
