Explanation:

The DNA could be dried -through the process of lyophilization- or stored, as a precipitate of ethanol, in liquid nitrogen (temperatures below -80 degrees Celsius). The aim is to reduce water in the stored samples as much as possible because the water can be involved in natural hydrolytic reactions (depurination, depyrimidination, deamination, and hydrolytic cleavage) that could degrade the nucleic acids of the DNA.

If the DNA is stored while being used regularly it is not advisable to store it as a precipitate of ethanol. It should be stored in aqueous form but in a slightly alkaline pH of about 8.5 to prevent acid-catalysed degradation processes.

Left atrium is known to be one of the four chambers of heart that receives oxygenated blood from the right and left pulmonary veins. This blood is pumps to the left ventricle through the mitral valve. However, left ventricle is responsible for pushing oxygenated blood through the aorta to the rest of the body.
