DNA-based genome

Explanation:

Prokaryotic cells are very different from eukaryotes. Its main feature is the lack of library individualizing the cell nucleus, the absence of some organelles and the small size that is believed to be due to the fact that they do not have membranous compartments originated by evagination or invagination. These cells have a DNA-based genome, including this DNA in the form of a non-protein associated ring (as in eukaryotic cells, where DNA is arranged in spiral and histone-associated filaments).

Eukaryotic or eukaryotic cells are more complex than prokaryotes. They have individualized nuclear membrane and various types of organelles. Most of the animals and plants we are used to are endowed with these cells. In addition to the differences between these cells and prokaryotic cells, there is a similarity between these two cells which is the DNA-based genome.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
