What does the acronym "DNA" stand for in forensic science?

In forensic science, "DNA" stands for deoxyribonucleic acid. This term refers to the molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses. DNA is composed of two strands that coil around each other to form a double helix, consisting of nucleotide units with a deoxyribose sugar, phosphate group, and nitrogenous base. This unique structure allows for the encoding of genetic information, which can be analyzed in various forensic applications, such as identifying individuals based on their genetic makeup or determining relationships between biological samples.

Understanding the correct terminology is essential for effective communication in the forensic field, as many investigations rely on accurate DNA evidence to draw conclusions about criminal cases or biological relationships. Other acronyms provided do not accurately describe DNA and would confuse those studying or working in forensic science.
