If a restriction site is altered, a higher molecular weight band will be observed.
Restriction enzymes are proteins synthesized by bacteria to protect itself against foreign DNA. These enzymes cut DNA at specific places.
This enzyme is used to detect mutations in the genome, particularly those at the sites of action of these restriction enzymes. A healthy subject is compared with the patient who is supposed to have cystic fibrosis. If their DNA migration is different, it means that their DNA is different and that there is a mutation at the restriction sites.
DNA and RNA perform different functions in humans. DNA is responsible for storing and transferring genetic information while RNA directly codes for amino acids and as acts as a messenger between DNA and ribosomes to make proteins.
The perivascular feet of the <u>endothelial cells</u> help create a blood-brain barrier.
<h3>What are endothelial cells?</h3>
Endothelial cells can be defined as those type of cells found in the inside lining of blood vessels, lymph vessels, and the heart.
Interestingly, the major function of the edothelial cells is that they release substances that control vascular relaxation and contraction as well as enzymes that control blood clotting, immune function and platelet (a colorless substance in the blood) adhesion.
So therefore, the perivascular feet of the endothelial cells help create a blood-brain barrier.
