There is no attached table, so it could not be told precisely which of the four molecules is the DNA. But, it is known that DNA consists of deoxyribose, guanine, and phosphate.
The base unit of DNA is called a nucleotide. The nucleotide consists of a nucleobase (adenine - A, thymine - T, cytosine - C, and <u>guanine -G</u>), a monosaccharide <u>deoxyribose</u>, and a <u>phosphate </u>group. <span>By knowing this, it is easy to choose which molecule of those is the DNA.</span>
