<h3>How is recombinant DNA produced?</h3>

Obtaining recombinant DNA is based on the molecular cloning technique. The process can be summarized as follows:

  1. The first step is to isolate a DNA fragment, which contains the gene of interest. Remember that each gene makes a protein.
  2. The gene of interest, now isolated, is placed in a medium with a fragment of circular bacterial DNA, the plasmid and the restriction enzymes.
  3. The bacterial plasmid has the ability to insert a fragment of DNA external to its own genome.

<h3>What is DNA and what is it for?</h3>

DNA is the structure responsible for the transmission of all genetic characteristics — such as eye, skin and hair color, physiognomy, among others — in the process of reproduction of living beings. Thus, the main function of DNA is to transport information contained in its sequences, called genes.
