Nucleotide monophosphates such as adenosine-5′-monophosphate (AMP), guanosine-5′-monophosphate (GMP), and cytidine-5′-monophosphate (CMP) and also deoxyribonucleotides (Herring testis DNA 100–2000 base pairs in length) have been successfully intercalated into MgAl-LDHs via ion-exchange reactions...
Where is the phosphate group in DNA? The phosphate group present in the nucleotide creates a covalent bond with the sugar molecule of the adjacent nucleotide to form a long chain of the nucleotide monomers. The sugar-phosphate groups form a backbone in the single strand of DNA. The phosphate...
A functionalized phosphoramidite nucleotide derivative can be added at particular points in the synthetic process to create labeled probes of known structure. Non-nucleotide phosphoramidites may also be used to produce modified probes containing fluorescent molecules, biotin, chelating groups, or spacer ...

Basic structure of DNA or deoxyribonucleic acid: A nucleotide is the basic of polynucleotide chain of DNA and each nucleotide is composed of three components - i) a nitrogenous base, ii) a pentose sugar and iii) a phosphate group. Nitrogen base is attached to the pentose sugar by an N-gl...
True or false? In a single nucleotide, the phosphate group is attached to the 5' carbon of the sugar unit. TRUE OR FALSE: 1. The phosphate attached to the 5' carbon of given nucleotide links to the 3' -OH of the adjacent nucleotide. 2. The -OH group on the...
The phosphate group is linked to the 5' carbon of the sugar in a nucleotide by a phosphodiester bond, not a glycosidic linkage. Glycosidic linkages are found in carbohydrates, connecting sugars to other molecules. - Conclusion: This statement is incorrect. 4. Statement 4: "All the four deoxy...
These findings are interpreted in terms of an absolute requirement of the nucleotide activatorsite in phosphorylase for a nucleotide with a dianionic phosphate. The implications of this for the role of the phosphate moiety in the proposed mechanism of activation are discussed. 展开 ...
DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide. The sugar is the 3' end, and the phosphate is the 5' end of each nuclei...
