Answer:
it condenses the DNA so that it can fit inside the cell.
Explanation:
Supercoiling is a level of genome packaging and is important for the packaging of the DNA which is about 2m in length inside a nucleus that is about 6microm. Supercoiling refers to the over (positive supercoiling) or under winding (negative supercoiling) of a DNA strand, and is an expression of the strain on that strand. Supercoiling is in compacting DNA, and also allows for the regulation of access of transcriptional machinery and other biological activities to the DNA and in turn gene expression. Certain enzymes such as topoisomerases are able to change DNA topology to facilitate access of DNA replication or transcription.
Make sure food is not left out for an excessive amount of time as this could cause it to enter the danger zone for temperature and allow bacteria to grow. To stay out of the temperature danger zone in the kitchen, make sure your refrigerators and freezers are set to the proper temperature.
<h3>Food is what?</h3>
- Any material consumed as food provides nutrition for an organism.
- Food comprises essential nutrients such carbohydrates, lipids, proteins, vitamins, and minerals and is frequently generated from plants, animals, or fungi.
- An organism consumes the substance, which is then absorbed by its cells to provide energy, support life, or stimulate growth.
<h3>What is temperature?</h3>
- Temperature is a physical quantity that expresses how hot matter is, or as a measure of the average translational kinetic energy per atom or molecule in the system.
- It is the detectable portion of the molar thermal energy of matter; a temperature difference allows heat transfer to occur, as energy flows from a hotter body to a colder body.

Answer:
D. Binding of p53 to Mdm2
It has nothing to do with Xray irradiation.
Explanation:
Mdm2 is a protein regarded as the main regulator of tumor suppressor protein P53. P53 Inactivation by mutation is seen as one of the most frequent alterations in tumors that affects humans.
The central binding p53 site of Mdm2 encloses amino acid. The binding of p53 to the central Domain is strengthened after the process of phosphorylation of the central Mdm2 domains.
A verdict of not guilty constitutes an acquittal. In other words, to find a defendant not guilty is to acquit. At trial, an acquittal occurs when the jury (or the judge if it's a judge trial) determines that the prosecution hasn't proved the defendant guilty beyond a reasonable doubt
Coarctation of the aorta can cause high blood pressure in the heart. This can cause the muscle of the heart's main pumping chamber (left ventricle) to become thick. Eventually, the function of the heart muscle could deteriorate if the condition isn't treated.
