GarryVolchara [31]

Answer:

A general decrease in transcriptional activation

Explanation:

When acetyl groups are added to histone proteins by acetyltransferase enzymes, the 30-nm chromatin fiber will not be formed because the proteins are prevented from doing so. This further destabilizes the chromatin structure and allows the occurrence of transcription. However, raising the cells to  40°C does not allow the acetyltransferase enzyme to function and hence the acetyl group will be hindered from being added to the histone protein which is the main target of the enzymes. Thus, transcription activation will be blocked because the chromatin and nucleosomes would remain stabilized.

Butanol was used in the production of:
hram777 [196]

Answer:

Synthetic rubber.

Explanation:

Polymerization can be defined as a type of chemical reaction in which molecules that are relatively small in size chemically combine to form a huge chain of molecules.

Simply stated, polymerization refers to a chemical reaction where two or more smaller molecules react to produce larger molecules of the same network or repetitive structural units.

In polymerization, the relatively small molecules are generally referred to as monomers while the larger molecules they produce are known as polymers.

Butanol was used in the production of synthetic (artificial) rubber through a fermentation process.

Infection occurs when the host is exposed to pathogens. what type of pathogen uses the cell's metabolism, and replicates itself
vladimir1956 [14]

Answer: Infection occurs when the host is exposed to pathogens. virus uses the cell's metabolism, and replicates itself while destroying the cell or changing the cell's genetic makeup.

Explanation:

  • A virus is a miniscule pocket of protein that contains genetic material.
  • Viruses pose a considerable challenge to the body’s immune system because they hide inside cells.
  • This makes it difficult for antibodies to reach them. Some special immune system cells, called T-lymphocytes, can recognise and kill cells containing viruses, since the surface of infected cells is changed when the virus begins to multiply.
  • Many viruses, when released from infected cells, will be effectively knocked out by antibodies that have been produced in response to infection or previous immunisation.
  • Antibiotics are useless against viral infections.  So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.

Hence virus are the pathogen that use the cell's metabolism. And replicate itself while destroying the cell or changing the cell's genetic makeup. viruses are so simple that they use their host cells to perform their activities for them
