DNA is deoxyribonucleic acid, which is insoluble in ethanol. In the process of centrifugation the addition of ethanol can aid to separate protein from its DNA.
<h3>What is centrifugation?</h3>
Centrifugation is a process of separating different molecules in a given sample that have different densities by rotating them in solution around an axis at high speed.
It is the frequently applied techniques in the molecular biology laboratory.
The addition of alcohol or ethanol to the sample followed by centrifugation can separate the proteins from its DNA.
Thus, the substance used to separate the proteins from the DNA is alcohol or ethanol.

The 2004 Sumatra Earthquake and Indian Ocean Tsunami gave us a vivid description of menace of major tsunamis. It also suggested that tsunami science and engineering were inevitable to save human society, industries, and natural environment.
An answer can be found in Japan. Japan is the country the most frequently hit by tsunamis in the world. The experiences are well documented and are continued as the local legends. In 1896, the tsunami science started when the Meiji Great Sanriku Tsunami claimed 22,000 lives. An idea of comprehensive countermeasures was officially introduced after the 1933 Showa Great Sanriku Tsunami. The major works taken after this tsunami, however, were the relocation of dwelling houses to high ground and tsunami forecasting that started in 1941. The 1960 Chilean Tsunami opened the way to the tsunami engineering by elaborating coastal structures for tsunami defense. The 1983 Japan Sea Earthquake Tsunami that occurred during a fine daytime cleared the veil of actual tsunamis. The 1993 Hokkaido Nansei-Oki Earthquake Tsunami led to the practical comprehensive tsunami disaster prevention used at present, in which three components, defense structures, tsunami-resistant town development and evacuation based on warning are combined.
The present paper briefs the history of tsunami research in Japan that supports countermeasures.
The answer is epithelium. In particular, stratified squamous epithelium. Epithelium is protective tissue that is found on<span> the outer surfaces of </span>organs and blood vessels<span> and </span><span>inner surfaces of </span>cavities<span> in many internal organs. Epithelium contains no blood vessels, and nutrients reach the epithelial cells through diffusion from the underlying tissue.</span>
