Respuesta :

The 8 DNA nucleotides will have 8 bases because each nucleotide contains one base.

Explanation:

Nucleotides are the building block or the structural unit of a DNA molecule.  

Each nucleotide is a polymer composed of a nitrogenous base attached to a pentose sugar group which is attached to a phosphate group.

The sugar and phosphate group form the outer framework while the bases form the inner structure of the DNA double helix. A hydrogen bond connects the sugar groups if neighboring nucleotides.

The common nitrogenous bases are adenine, thymine, cytosine and guanine. These bases contain the genetic information and are coded respectively to produce the required phenotype.

On a single double helix DNA strand, there are two pairs of DNA nitrogenous bases. So, 8 DNA bases will have 4 pairs of bases or 8 single bases.

A single nucleotide is composed of a sugar (pentose), a phosphate group and a nitrogenated base (adenine, guanine, cytocine, thymine or uracil). One base per nucleotide. If I have 8 DNA nucleotides, then, I have 8 bases.

  • Macromolecules such as DNA and RNA are polymers composed of nucleotides joint by their extremes.

  • Nucleotides are monomers. The elements composing each of them are a sugar molecule, joined with a phosphate group and a nitrogenated base.

  • Nitrogenated bases are purines and pyrimidines. Adenine and guanine derive from purines, while Thymine or Uracil and Cytosine derive from Pyrimidines.

  • The nucleotidic sequence specifies the genetic instructions to the correct development and functioning of the organism.

  • A sequence of three nucleotides composes a codon. And each codon codifies for one amino acid.

According to this information, each nucleotide is composed of a phosphate group, a sugar -pentose- and a nitrogenated base.

Hence,  in a sequence of eight nucleotides, there are the same amount of bases.

One base per nucleotide   ⇒    8 nucleotides, 8 bases.
