RNA has great capability as a genetic molecule; it once had to carry on hereditary processes on its own. It now seems certain that RNA was the first molecule of heredity, so it evolved all the essential methods for storing and expressing genetic information before DNA came onto the scene.
Answer:
The correct answer is- A) two, B) yes, the number is the same as monosaccharides.
Explanation:
There are three atoms are present in a molecule of water which includes two atoms of the hydrogen and one atom of the oxygen. The hydrogen atom is two times larger in the number of the oxygen atom in a single molecule of the water.
In monosaccharides, the ratio of the atoms of carbon, hydrogen, and oxygen is 1:2:1 which means one hydrogen atom would be twice in the number of the carbon and oxygen atoms in a single molecule of monosaccharide molecule.
Thus, the correct answer is - A) two, B) yes, the number is the same as monosaccharides.
