DNA, which stands for deoxyribonucleic acid, is a molecule that supplies the genetic instructions that tell living creatures how to develop, live and reproduce. DNA can be found inside every cell and is passed down from parents to their offspring.
What is actually DNA produced from?
DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C), and together, these serve as the “letters” that make up the genetic code of our DNA.
Nucleotides is connected together with her in order to create a couple of long strands that spiral in order to make a structure entitled a double helix.
