If the expression of every gene depends on a set of transcription regulators, then the expression of these transcription regulat

ors must also depend on the expression of other transcription regulators, and their expression must depend on the expression of still other transcription regulators, and so on. Cells would therefore need an infinite number of genes, most of which would code for transcription regulators?

Answer:

Transcriptional regulators function to regulate the expression of different genes and also to affect the expression of other transcriptional regulators, thereby the combination of a few transcriptional regulators is sufficient to modulate gene expression patterns

Explanation:

Transcriptional regulators are able to control gene expression by binding to cis-regulatory elements on the genome. For example, in plants, MADS-box proteins are transcriptional regulators that contain an evolutionary conserved DNA-binding domain (i.e., MADS-box domain) which regulate simultaneously the expression of many different genes by binding to a conserved DNA motif called CArG box [CC(A/T)6GG] located in the promoter region of many genes expressed at specific stages of plant development. Within the cell, transcription regulators function not only by controlling the expression of different genes but also by affecting each other's activity, thereby creating different combinations where the expression of a limited number of transcription regulators is sufficient enough to regulate gene expression patterns.

HELP!! WILL INCLUDE LINK
ankoles [38]

First of all, I want to say that I was literally learning about this stuff not 10 minutes ago. That is a re.tardedly creepy coincidence.

1.) Science is used mostly through the field of forensics in order to study crime scenes, collect data like fingerprints and hair fibers to try to identify the suspect, as well as use things like blood splatter to try to recreate what happened during the crime. this data is then used as evidence, either for or against a suspect, in order to sway the jury's opinion.

2.) Television shows like CSI have certainly raised awareness. Forensics, which was a formally unknown and untalked about profession is now in the spotlight. However, it can lead to some problems, such as skewing jurors' expectations of what to expect from forensic specialists.

3.) The scientific method consists of five steps:

-Make an observation.

-Ask a question.

-Form a hypothesis, or testable explanation.

-Make a prediction based on the hypothesis.

-Test the prediction.

The feedback loop occurs when you use the end conclusion to form another hypothesis to another experiment. Essentially, the feedback loop means that you are continually improving upon your experiment.

4.) In a criminal trial, a suspect or defendant is being accused of a crime. It is up to the prosecutor to prove that the defendant is guilty of that crime. It is up to the defense attorney to defend the defendant and prove that he is not guilty. It is up to the judge to listen to all the evidence and afterwards to give his verdict. The scientists can be used by either the prosecutor or defense attorney to bring forth evidence that can support either of their sides.

5.) Control samples are any type of well-known forensic samples that are used to assure analysis is properly performed so that results are reliable.

6.)It was helpful for scientists to compare results from the burnt debris and unburned background material from the area to see if the gasoline was present in the unburned samples.

7.) The analytical sciences used in the courtroom are very reliable because they go through careful screening and are measured against control samples so that they are accurate.

8.) Bias can seriously mess up a case. Say, if the forensic scientist in charge of testing and taking samples from the crime scene is an acquaintance of the suspect, he could purposely mess up the testing so that he clears his friend.

Question 3 (2.25 points)
grigory [225]
D. Conclusion

After gathering data in support of a hypothesis, you can make a conclusion.

A hypothesis has to be tested multiple times by multiple researchers to become a theory. A fact has to be proven multiple times as well (but theory is a much better word).

Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from hap
vekshin1

Answer:

Phenytoin and ethosuximide are drugs that slow the recovery of the sodium channel during the inactivated state.

That is to say, they prolong the inactivation state of the channel, thus generating that in this way the neuron remains in resting potential and the action potential causing the epileptic attack is not triggered.

On the other hand, these drugs, according to the bibliography of the book "Golan, 3rd Edition, Principles of Pharmacology" have a use-dependent affect capacity, this means that those sodium channels that have more activity will be more affected, in this way Not only is epileptic shock avoided, but if the same happens independently in any neuron, it will not be able to propagate the action potential to its neighboring neurons, therefore the surrounding neurons will not be stimulated and will not be fulfilled. with the sudden rapid discharges that are the most dangerous in some cases of severe epilepsy.

It is important to understand that these drugs affect the ion channels responsible for exciting neurons, that is why by inhibiting them, a constant rest of these neurons is promoted, and they are unable to generate abrupt discharges and dissemination of the electric charge. among them generating epileptic shocks.

The ions in neurons are in charge of indicating or modulating the different neuronal states, if they are inactive, open or closed, they will directly affect the membrane potential, that is, the positive or negative charge of the neuron's membrane.

Explanation:

In order to finish completing the question, these drugs are excreted through the p450 protein, that is why if this excretion system becomes saturated because another drug is consumed that is excreted in the same way, these antiepileptics will remain longer in use. blood and in the body, generating a greater effect and enhancing adverse effects on the central nervous system.
