During the sanger dideoxy sequencing method of determining the sequence of DNA, the purpose of the dideoxy nucleotide is to amplify a target segment of DNA.
<h3>What is DNA?</h3>
This is referred to as deoxyribonucleic acid and is the genetic material of living organisms. They are composed of chains of nucleotides which ensures that traits are passed from the parent to offspring.
The purpose of the dideoxy nucleotide in DNA sequencing is to amplify a target segment of DNA so that the DNA sequence can be determined precisely.

These are examples of homologous structures. Homologous structures are similar because they are inherited from a common ancestor, they are examples of organs or structures that appears in different animals, underlining anatomical commonalities which is evident that they have a common ancestor. Analogous structures on the other hand are structures that are similar in unrelated organs.
