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)
Answer:
Building and repairing cells
I believe the condition is infestation. Infestation is the state of being invaded or overrun by pests or parasites. It can also refer to the actual organisms living on or within a host. For example being invaded by ectoparasites such as lice, mites, or ticks. It may also refer to the presence of an unusually large number of insects or animals in a place, typically so as to cause damage or disease.
Evoultion is the change of the allele frequencies and the inherited traits of a population over time.
The idea of evolution is that the species change over time. The proposed mechanism of evolution is natural selection. Natural selection favors inheritable trait, suitable for survival and reproduction. Organisms with such traits will tend to leave more offspring than others, and thus will evolve over time.
