Nucleotides are monomers composed of sugar and phosphate groups and a nitrogenated base. Several nucleotides compose DNA and RNA.
<h3>What are nucleotids?</h3>
Nucleotides are monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base.
Monomers are composed of carbon, oxygen, and hydrogen atoms, which establish covalent bonds.
Several monomers comprise a polymer. In this way, several nucleotides joined by their extremes compose the nucleic acids.
- Nitrogenated bases are molecules carrying nitrogen and exhibiting the chemical properties of a base. These are purines and pyrimidines.
DNA ⇒ Adenine, Guanine, Thymine, and Cytosine.
RNA ⇒ Adenine, Guanine, Uracyl, and Cytosine
Adenine pairs with thymine or uracil, while guanine pairs with cytosine.
- Sugar group: Sugar is always a pentose.
DNA sugar group contains deoxyribose, with hydroxyl modifications.
RNA sugar group contains ribose with no hydroxyl modifications.
Nucleotides have a certain order or sequence in nucleic acids, which is significant since these sequences carry biological information necessary to carry out cellular functions.
