How does analyzing dna profiles using the gel electrophoresis tool allow you to draw both qualitative and quantitative conclusions about the likely identity of the suspect in this case?

The analysis of DNA profiles using gel electrophoresis involves loading of the DNA samples in the well of the gel matrix. An electric potential gradient is present across the length of the gel that moves the DNA through the gel matrix. The gel is imaged under a UV lamp to show the presence of the required bands of DNA to give a qualitative estimate. The thickness of the band can give the quantitative measure of the amount of mRNA that is being made in the cell.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
