n cancer cells one allele of the tumor suppressor gene p53 is frequently mutated so that the protein is inactive, not produced,

or deleted. The other allele will usually have a normal sequence and the promoter remains intact but the gene is not expressed. Sequencing with sodium bisulfite modification of DNA can be used to detect which cytosines are methylated. If the cancer cell DNA is sequenced what would be the anticipated results?

Answer:

If the cancer cell's DNA is sequenced than the anticipated results will be that the cytosines in or close to the promoter region will get methylated. It has been stated that in the cancer cells one allele of p53 is mutated and the other allele, however, of exhibiting an intact promoter, does not express the protein.  

Thus, it shows that the expression in the other allele gets suppressed by methylation rather than by mutation. Methylation generally takes place in CpG islands in or close to the promoter region and therefore inhibits transcription.

How would an x-ray technician position the camera to produce a frontal view of a patient's abdominal cavity?
leva [86]

Answer: Option A. "In front of the patient, pointing at his navel"

Explanation:

The X-ray of abdominal cavity is known as Abdominal x-ray. It has same principle as X-ray and uses ionizing radiation to take pictures of inner parts of abdominal cavity such as intestine, stomach, liver and spleen. it is used to diagnose patients with vomiting, unexplained pain, and nausea.

While diagnosing  patient's abdominal cavity, x-ray technician position the camera in front of the patient, pointing at his navel in order to produce a frontal view of abdominal cavity.

Talking about a x-ray machine, it is a compact apparatus which can be taken to the patient in a hospital bed or the emergency room. The x-ray tube connects flexible arm which further extends towards the patient and an x-ray film holder (image recording) plate is placed under the patient.

The technologist will ask the patient to take position on the x-ray table or bed and will position x-ray machine over the abdominal area of the patient, in order to take the frontal view of abdominal cavity. The patient will be asked to hold their breathe to get a clear picture. The technician will turn on the x-ray machine that allows  x-ray machine  to produce a small burst of radiation which passes through the abdominal area and records the frontal view of  patient's abdominal cavity. As a result, soft tissue shows up in shades of gray and air appears black while bones appear white on the x-ray, through which patient can be diagnosed.

Hence, the correct option is A "In front of the patient, pointing at his navel".

The initial stage of atherosclerosis is characterized by accumulation beneath the endothelium of excessive amounts of?
kogti [31]

The initial stage of atherosclerosis is characterized by accumulation beneath the endothelium of excessive amounts of ​LDL.

  • The accumulation of lipids, cholesterol, and other chemicals in and on the artery walls is known as atherosclerosis. The accumulation is known as plaque.
  • The build-up of lipids and fibrous components in the major arteries is a hallmark of the degenerative illness known as atherosclerosis. A picture of a typical artery's anatomy can be found in Foam cells, or subendothelial accumulations of cholesterol-engorged macrophages, are the earliest lesions of atherosclerosis.
  • Nitric oxide and prostacyclin are two chemicals that are produced by your endothelium. These maintain the fluid in your blood and stop it from clotting when it shouldn't. These compounds' insufficient production is a symptom of various diseases, which raises your risk of clotting.
