In which ways can the individual steps of this process be regulated to lead to higher or lower expression of a particular protei

Dahasolnce [82]

Answer:

There are many points at which eukaryotic gene expression can be controlled, through pretranscriptional control, transcriptional control, and posttranscriptional control

Explanation:

The pretranscriptional control determines the accessibility of chromatin to the transcription machinery. It is affected by supercoiling and methylation. It is also known as epigenetic regulation, and it does not depend on the sequence but on the conformation of the DNA.

While transcriptional control determines the frequency and / or speed of transcription initiation through the accessibility of the start sites, the availability of transcription factors and the effectiveness of promoters.

The post-transcriptional control is the one that is exercised once the transcript has finished synthesizing. It can be of several types:

• Maturation control: As the RNA adjustment can be made.

• Transport control: Most RNA has to go out to the cytoplasm to perform its function. For this they have to cross the pores of the nuclear membrane, where you can select the RNAs that will be transported and those that will not.

• Stability control: The half-life of RNA can be regulated by the expression of RNAs or mRNA stabilizing proteins in the cytoplasm.

• Translational control: It is exercised on the frequency with which the mRNAs begin to be translated. It can also affect the frequency with which proteins mature and the availability of enzymatic effectors.

<h3>What are viruses bacteria and parasites?</h3>

Some bacteria sleep in and on our bodies and don't cause problems.

<h3>Which are infectious diseases?</h3>

The flu, measles, HIV, streptococcal sore throat , COVID-19 and salmonella are all samples of infectious diseases. Cancer, diabetes, congestive coronary failure and Alzheimer's disease are all examples of noninfectious diseases.

What are the causes of disease?

Similarly, diseases are caused by different microorganisms and may be classified as diseases caused by bacteria, fungi, viruses etc. Some diseases also are caused by multicellular organisms such as worms.
