What are some interesting facts about nucleic acids?

Nucleic acids are DNA, mRNA, and tRNA, and they are the building blocks of life. Each nucleic acid is made of up five parts: uracil, thymine, cytosine, adenine and guanine.

Humans need 20 amino acids and five nucleotides to survive. Nucleotides are made of a five-carbon sugar, a nitrogen base and an ion of phosphoric acid.

DNA, or deoxyribonucleic acid, is one of the most important nucleic acids in the human body. It contains special genetic code for every cell in the body. In essence, DNA is a long, double-helix chain of nucleotides and the nucleic acid in each strand of DNA must be able to replicate itself during cell division.
