If the binding of the third strand in the major groove occurs at site where RNA polymerase binds to a gene, then third stand can inhibit gene transcription. (2019, July 23). Finally, a specialized enzyme called a kinase adds two phosphate groups using adenosine triphosphate (ATP) as the phosphate donor to form ribonucleoside triphosphate, the immediate precursor of RNA.

This is possible because the chemical properties of nucleotides allow 5 carbons to bond to multiple phosphates. The journal Nucleic Acids Research regularly publishes special issues on biological databases and has a list of such databases. Image of the components of DNA and RNA, including the sugar (deoxyribose or ribose), phosphate group, and nitrogenous base. More about Kevin and links to his professional work can be found at www.kemibe.com. (2016) Metal ion induced heterogeneity in RNA folding studied by smFRET. The Biological Function of Nucleic Acids Hermann Heumann & Wolfram Zillig Chapter 1112 Accesses Abstract The function and organization of cells and organisms are determined by the type and quantity of protein contained therein. The primary purines are adenine and guanine in both RNA and DNA. Cold Spring Harbor Monograph Series, Cold Spring Harb. The two strands are held together by H-bonding between the complementary base pairs (A pairs with T and G pairs with C) as shown in Figure \(\PageIndex{10}\) below. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that . A group of three nucleotides is called a codon. Of course the hydrogen bonds are not between backbone atoms but between side chain bases in double stranded DNA. Biologydictionary.net Editors. Its structure serves that purpose well. Ribonucleic acid (RNA), unlike DNA, is usually single-stranded. A nucleic acid is a chain of nucleotides which stores genetic information in biological systems.
