Answer:
As the transcription process proceeds, a variety of secondary structures forms by the nascent RNA. t takes place due to the fact that portions of the transcript as complementary base pairs form.
The transcript could be pause but terminate, the hairpin loop causes RNA Pol to pause. There are two different ways to terminate transcription in prokaryotes
- intrinsic termination: in this no external factors required
- Rho protein termination: binds to end of msg and moves along by ATP hydrolysis to catch up (rho is faster)
Elephants have pointy tail because they need it to become more streamlined and for their aerodynamics. Being streamlined and having aerodynamics helps them to have a little resistance to air and water flow. It also helps them to increase speed and for ease of movement.
