A nucleotide always contains a nucleoside that binds the one to three phosphate groups. A nucleoside is always composed of a pentose sugar and a nitrogenous base, which are the same as a nucleotide would have. Examples of nucleosides includecytidine, uridine, guanosine, inosine thymidine, and ade...
What is a subunit of nucleic acid formed from simple sugar, a phosphate group, and a nitrogenous base? Which of the following is not a nucleotide in DNA? a) adenine b) guanine c) cytosine d) uracil Which of the following is true about the ...
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-glycosidic linkage forming a nucleoside. A pho...
These are polymerized from nucleotides (the monomers) each constituted from a sugar, a phosphate group, and a “base” derived from a purine or pyrimidine (aromatic heterocycle). The sugar and phosphate are polymerized by eliminating water to form a linear backbone, with the bases playing the ...
What is a nucleotide? A. The combination of nitrogenous base, sugar, and phosphate group B. Phosphate units C. Deoxyribose D. The combination of deoxyribose and a phosphate group When you exercise, lactic acid, CH_3CH(OH)COOH, is produced as a product of metabolism. The l...
Which of the following is not part of a nucleic acid? a. Pentose sugar. b. Nitrogenous base. c. Fatty acid group. d. Phosphate group. What are the three major food macromolecules digested in our GI tract? Identify the four important biological macromolecules and a reason for their ...
The core ring, leading ultimately to a nitrogenous base, is formed first during UMP biosynthesis (Fig. 1). The sugar moiety, D-ribose issued from phosphoribosyl pyrophosphate (PRPP) is then incorporated to the structure15. Figure 1 Current in vivo pyrimidine biosynthesis along the orotate pathway...
ATP is known as energy currency of the cell and it is a nucleotide formed by the combination of adenine as a nitrogenous base, ribose sugar, and triphosphate. It is found in free cells which breaks to form energy by breaking it's high energy phosphate bonds. The high energy phosphate bond...
