The DNA sequence is composed of four types of nitrogenous bases: adenine (A), cytosine (C), thymine (T) or guanine (G), together with a phosphate group, there is variability due to changes in said sequence of DNA of a gene.
What is DNA?
DNA is a nucleotide biopolymer, that is, a long molecular structure made up of segments (nucleotides) made up of a sugar (ribose) and a nitrogenous base.
- In the sequence of this compound, all the genetic information of a living being is stored, essential for protein synthesis and for reproductive inheritance.
- The variety of traits in humans are due to mutations at the molecular level that would consist of a change in the sequence of nitrogenous bases in DNA.
Therefore, we can conclude that the DNA molecule is a long structure of nucleotides, each nucleotide is distinguished from the others in the nitrogenous base it has, and all together make up the DNA sequence.
