What are the building blocks of DNA and RNA?
Nucleotides are the basic building blocks of DNA and RNA, two molecules essential for life as we know it. Molecules of both DNA and RNA serve as the genetic code that uniquely identifies every living organism.

Assemblies of polynucleotide strands are called nucleic acids, DNA and RNA. Nucleotides are extremely important because they serve as the fundamental bits of information in DNA, analogous to the binary 1 and 0 of a digital computer.
How do nucleotides bond?
Nucleotides bond to form polynucleotide chains. These polynucleotide chains form by a dehydration reaction, in which the sugar in one nucleotide is bonded to the phosphate group of another and a water molecule is removed. These phosphodiester linkages are what form the sugar-phosphate backbone of strands of DNA and RNA.

What is the backbone of sugar phosphate?
The combination of ribose or deoxyribose and phosphate group forms the sugar-phosphate backbone. The nitrogenous base is attached to the sugar molecule. The addition of a phosphate group to the nucleoside created by sugar and nitrogenous base forms a nucleotide.

In RNA, adenine pairs with uracil and guanine with cytosine. The following images show the chemical structure of each type of monomer, where the pentagonal shape of the monosaccharide and its attached phosphate group and specific nucleobase are clearly defined.
What are the elements that make up a nucleic acid chain?
The five elements necessary to construct a nucleic acid chain are carbon, hydrogen, oxygen, nitrogen, and phosphorus. The addition of phosphorus makes nucleic acid different to other categories of biocompounds, namely carbohydrates, lipids, and proteins.
How many nitrogen atoms are in a single ringed form of DNA?
Single ringed forms, known as pyrimidines, contain between two and three nitrogen atoms and are smaller and shorter. This is important in the double-strand feature of DNA and the process of translation, as only certain pairings of nitrogenous bases are possible (Watson-Crick pairings).
Can adenine and guanine bond?
This also tells us that adenine and guanine cannot create a double-strand bond together. In RNA, other base combinations are possible and are known as non-Watson-Crick pairings. In Watson-Crick pairings, larger bases, adenine, and guanine will never pair with each other.

The code is read by copying stretches of DNA into the related nucleic acid RNA in a process called transcription.
How does DNA differ from RNA?
One DNA or RNA molecule differs from another primarily in the sequence of nucleotides. Nucleotide sequences are of great importance in biology since they carry the ultimate instructions that encode all biological molecules, molecular assemblies, subcellular and cellular structures, organs, and organisms, and directly enable cognition, memory, and behavior ( see Genetics ). Enormous efforts have gone into the development of experimental methods to determine the nucleotide sequence of biological DNA and RNA molecules, and today hundreds of millions of nucleotides are sequenced daily at genome centers and smaller laboratories worldwide. In addition to maintaining the GenBank nucleic acid sequence database, the National Center for Biotechnology Information (NCBI, https://www.ncbi.nlm.nih.gov) provides analysis and retrieval resources for the data in GenBank and other biological data made available through the NCBI web site.
