DS DNA, also known as double-stranded DNA, is the genetic material that carries the genetic information in all living organisms. There are several synonyms that can be used to refer to DS DNA, including duplex DNA, double helix DNA, or antiparallel DNA. All of these terms refer to the structure of DS DNA, which consists of two complementary strands joined together by hydrogen bonds. In addition, DS DNA can also be referred to as genomic DNA, as it is the DNA that is found within the nucleus of a cell and is responsible for encoding an organism's genetic traits. Regardless of the synonym used, DS DNA remains a critical component of life and the foundation for all living organisms.
