What DNA is
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
What DNA does
DNA contains the instructions needed for an organism to develop, survive, and reproduce. DNA sequences must be converted into messages that can be used to produce protein, which are the complex molecules that do most of the work in our bodies.
How does DNA copy itself?
It’s DNA is duplicated because the two strands of the DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partners
the bindings are: (A) with (T), (G) with (C), (T) with (A), and (C) with (G)
