The most important macromolecules are nucleic acids. DNA and RNA, which carry the genetic information and translate it for protein building, for the correct functioning of the cell.
Nucleic Acids
Nucleic acids are DNA and RNA.
They are macromolecules composed of different nucleotides joined by their extremes.
Nucleotides are subunits or monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base.
Nitrogenated bases are molecules carrying nitrogen and exhibiting the chemical properties of a base.
Nitrogenated bases are purines and pyrimidines.
- DNA ⇒ Adenine and guanine, Thymine and Cytosine.
- RNA ⇒ Adenine and guanine, Uracil and Cytosine.
The nucleotidic sequence codifies or specifies the genetic instructions to the correct development and functioning of the organism.
DNA molecule keeps the genetic information about the sequence of amino acids in the protein, and RNA is in charge of translating that information .
Hence, the most important macromolecules are DNA and RNA, which carry the genetic information and translate it for protein building, for the correct functioning of the cell.
