For the human body, if there is no nucleic acid in the cell, the cell division can not be normal, can not be normal translation of proteins, the cell will gradually apoptosis, the cell once apoptosis, can not be normal metabolism and heredity, loss of function. Nucleic acid is a biological macromolecule composed of a variety of nucleotides, including deoxyribonucleotides and ribonucleic acid, is the human body to carry genetic information, in the human body, only mature red blood cells do not have a nucleus, and thus there is no nucleic acid, which is a normal situation. If there is no nucleic acid in other cells, which in turn cannot translate the proteins needed by the human body, the cells cannot carry out a series of life functions such as normal growth, division, metabolism and heredity, and the cells will gradually die and lose their functions.
