This condensation reaction is similar to that in which a peptide bond is formed between two amino acids (Chapter 3). Thus a single nucleic acid strand is a phosphate-pentose polymer (a polyester) with purine and pyrimidine bases as side groups. The links between the nucleotides are called phosphodiester bonds.
Also, the nucleobases found in the two nucleic acid types are different: adenine, cytosine, and guanine are found in both RNA and DNA, while thymine occurs in DNA and uracil occurs in RNA.
The main role of nucleic acids is to store information that is used to make proteins. Nucleic acids come in two main forms: deoxyribonucleic acids, also known as DNA, and ribonucleic acids, also known as RNA. The main function of DNA is to store the genetic information that cells in the body need to function.
The two main types of nucleic acids in your body are called deoxyribonucleic acid, DNA, and ribonucleic acid, RNA. There are several sub-types of RNA, including messenger RNA, mRNA, transfer RNA, tRNA, and ribosomal RNA, rRNA. ... DNA stores your genetic information in the nucleus of your cells.
