The linkage between individual nucleotides in DNA is known as a phosphodiester bond because— two esters are connected by a single covalent bond whose formation is catalyzed by a phosphate. a double bond is formed in the process of esterification of a phosphate group. a nucleoside diphosphate is involved and each phosphate forms one ester. a single phosphate is esterified to two deoxyribose units. two bonds are phosphorylated into one single bond
Which one of the following statements about nucleic acids is correct? Multiple Choice NTPs can be incorporated into either DNA or RNA molecules, but dNTPs can only be incorporated into DNA molecules A nitrogenous base, 5-carbon sugar, and two phosphate groups would most accurately be referred to as a nucleotide diphosphate. During nucleic acid synthesis, the phosphate group at the 3' carbon of the incoming monomer is covalently linked to the hydroxyl group at the 5' carbon of the existing macromolecule. RNA and DNA have all the same pyrimidine bases in them, but differ in the selection of purine bases. A nucleic acid found in a cell with the sequence GCCTTATCGCG would most likely be found paired with another molecule in double-stranded form.
Which of the following is correct regarding nucleotide structure? Removal of the ribose-phosphate groups from thymidylic acid or thymidylate yields thymidine Removal of the ribose-phosphate groups from cytidine yields cytosine Removal of the phosphate group from guanylic acid or guanylate yields guanine. Removal of the phosphate group from adenylate or adenylic acid yields adenosine

Select the one statement that accurately describes the difference between a nucleotide and a nucleoside: Nucleosides are found in DNA, whereas nucleotides are found in RNA Purines are only found in nucleotides. Nucleosides contain only deoxyribose sugars. A nucleotide is a nucleoside with a phosphate ester linked to the sugar. None of the these are correct. E00000
In a DNA oligonucleotide, two nucleosides are linked together with a: Phosphodiester bond Phosphatic bond Phosphoester bond Glycosidic bond
In DNA the nucleic acid bases form hydrogen bonds between them, which are responsible for the formation of the double-stranded helix. A hydrogen bond donor is defined as any hydrogen atom that can participate in a hydrogen bond, whereas a hydrogen bond acceptor is defined as any atom that can “receive” that hydrogen atom to form a hydrogen bond. How many hydrogen bond acceptors does guanine (shown below) have? a) 3, b) 5 c) 4 d) 6 e) 7
