DNA
DNA, or Deoxyribonucleic acid, is a long and thin molecule that is necessary to create and sustain life for all organisms and even many viruses. It stores all genetic instructions that tell every individuals cell what to do. DNA is made out of deoxyribose, a phosphate group, and nitrogen bases. DNA is packaged into chromosomes inside the nucleus of every cell.
The information in DNA is stored as a code made up of four nitrogen bases: adenine (A), guanine (G), cytosine (C), and thymine (T). These bases pair up using hydrogen bonds to form the rungs of the twisted ladder, or double helix, shaped DNA. Adenine and thymine are always paired together in DNA. Guanine and cytosine are also always paired together.
The pattern which these four bases are placed in is really what makes us all different. While 99% of the pattern is the same for all organisms in the species, there is a completely unique
1% inside of all organisms that set us each apart. For more information about DNA you can watch a video about it here!
