The structural formula for the nucleotide
Concept Introduction:
The Nucleotide is the component of Nucleic acid which is a component of DNA and RNA. The Nucleotide consists of three components-Nitrogenous base (heterogeneous aromatic amine base), five membered sugar molecule and phosphate group. The Nitrogenous bases are Purines (Adenine, Guanine) and Pyrimidines (Uracil, Cytosine, Thymine). The five membered sugar molecule may be D-Ribose or 2-Deoxy-D-Ribose sugar. The Phosphate base is linked to sugar molecule at
Nucleotide = Nitrogenous base + Sugar molecule + Phosphate ion

- Suppose that 28% of the nucleotides in a DNA molecule are deoxythymidine 5'-monophosphate, and that during DNA replication the percentage amounts of available nucleotide bases art 22% A, 22% C, 28% G. and 28% T. Which base would be depleted first in the replication process?arrow_forwardThis is a segment of a nucieic acid. (a) is this a segment of RNA DNA and name each nucieotide. (g) NH2 но NH2 0=P-O NH2 H H 0=P-O O=P-Oarrow_forwardThere are two families of nitrogenous bases. The pyrimidines have one six-membered ring carbon and nitrogen atoms while purines are larger with a six-membered ring fused to a five -membered ring. Identify the type of nitrogenous base from monomer nucleotides. How can you tell?arrow_forward
- How many different sugars and how many different heterocyclic bases are available , respectively , for incorporation into a nucleotidearrow_forwardDraw an example of the followings: 1- an amino acid; 2- a small peptide; 3- a DNA nucleotide; 4- an RNA nucleotide.arrow_forwardIdentify if the following is a pyrimidine/purine nucleotide or a pyrimidine/purine nucleoside and write whether the sugar moiety is a ribose or deoxyribose.arrow_forward
- Which statement best explains the chemical differencesbetween DNA and RNA? (a) DNA has two different sugarsin its sugar–phosphate backbone, but RNA only has one.(b) Thymine is one of the DNA bases, whereas RNA’s correspondingbase is thymine minus a methyl group. (c) TheRNA sugar–phosphate backbone contains fewer oxygenatoms than DNA’s backbone. (d) DNA forms double helicesbut RNA cannot.arrow_forwardWhich nucleotidels) will base pair with the following nucleotide: NH2₂ G VA U ST SC DNA origins of replicationarrow_forwarddraw the structuresof the common ribonucleotidearrow_forward
