What are the similarities and differences between ribonucleic acids (DNA, RNA)?

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are extremely important core substances in biological cells. The difference is that DNA mainly exists in the nucleus in the form of biological genetic information (genes). It can give instructions and dominate the synthesis of protein. RNA mainly exists in cytoplasm. RNA does not carry genetic genes, but it is the executor of DNA information instructions and mainly participates in the synthesis of protein in human body. In addition, the basic components of DNA and RNA are different. For example, pentose in DNA is D-2 deoxyribose, while RNA is D- ribose.

It should be pointed out that exogenous nucleic acids, whether it is nucleic acid nutrition or any biological nucleic acid ingested by human body from diet, are not absorbed in the form of gene fragments with genetic functions, but in the form of nucleic acid raw materials. After they enter the human body, they can be digested and degraded into nucleotides, nucleosides, bases, pentoses and phosphoric acid, and their decomposition products are basically the same. Therefore, whether nucleic acid nutrition contains RNA or DNA, its nutritional and health care functions are the same.
