First, let's review a few definitions. DNA, deoxyribonucleic acid: an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms, constructed of two nucleotide strands coiled around each other in a ladderlike arrangement with the side pieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine: the genetic information of DNA is encoded in a sequence of the bases and transcribed as the strands unwind and replicate. Molecular systematics is a scientific discipline that uses nucleic acids or other molecules to infer. evolutionary relationships between different species.
