Ribosomes produce proteins and the nucleus is the main control center for the cell
Answer:
The ability of sequences within the leader mRNA to pair with one another and form stem-lopp structures
Explanation:
A form of feedback regulation controls the trp operon by regulating transcription termination, a mechanism referred to as Attenuation.
-In the presence of high concentrations of tryptophan, RNA polymerase ceases transcription shortly after initiation in a region called the leader sequence.
-If the concentration of tryptophan is low, transcription does not terminate until the entire operon is transcribed. The mechanism of attenuation links alternative RNA secondary structures to transcription termination.
-Immediately after transcription, RNA from the leader region folds into one of two alternative secondary structures.
-One of these structures is a transcription termination signal that stops RNA polymerase from continuing to the end of the operon.
-The alternative structure does not contain a transcription termination signal and allows transcription of a single mRNA that encodes all the structural genes.
-The decision as to which of the two alternative RNA structures formed is regulated by the concentration of tryptophan.
In a neuroscience experiment, the one of these would best indicate LTP is Stronger and more frequent action potentials in the postsynaptic neuron.
<h3>What is long-term empowerment?</h3>
Long-term potentiation (LTP) is the increase in postsynaptic responses over hours, days, or weeks after brief repetitive stimulation of presynaptic afferents.
However, for study purposes, LTP is commonly divided into three sequentially occurring phases: short-term potentiation, early LTP, and late LTP.

Answer:
Yes it is (we already have one)
An international orbiting space station would be a great idea! We could use the space station as a refueling point for passing spaceships. This could helps us achieve things such as space exploration, mars/moon colony, or even contact with other unearthly organisms. This could also allow us to conduct space research.
No it isn't
An international orbiting space station is a horrible idea! The first thing to think about is the money. This would put the entire area in stasis as we try to raise money for the space station. We also need contact with the humans/robots in space! Building a space station would confuse other nations as to what we plan to do with said space station. This could cause a war of some sort.
