Ascientist wants to make a dna fingerprint and she has used polymerase chain reaction pcr and restriction enzymes. what should her next step be

The first step will be amplifying the DNA sample using the PCR machine. Only small sample may be used for DNA fingerprinting. the DNA is being amplified by a way f heating so as it can denature to single-stranded where tag polymerase is being synthesized by an enzyme.

step2. Take the restriction enzyme then  and also the product then mix them together.

step3. by use of gel electrophoresis you learn the sample.

step 4. both results for the fingerprints and the ones you were testing so as to find if there is any banding.

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.
