How does DNA profiling work?

Two or more DNA samples are compared to find a match.

Genes are added or removed from an organism.

DNA is cut out of an organism.

A DNA sample is compared with an RNA sample

"Two or more DNA samples are compared to find a match"

Explanation:

DNA Profiling is where somebody using Sanger Sequencing and electrophoresis compare the DNA strands of two people to look for similarities and differences.

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.
