DNA, RNA, Proteins (1 of 4) DNA
DNA is a long, double-stranded molecule twisted into a helix. It is composed of a chemical code (represented by the letters A, T, G, and C) that describes how to make proteins.
DNA, RNA, Proteins (2 of 4) RNA
RNA is similar to DNA, but it is shorter and single-stranded. RNA can carry an "imprint" of DNA information and take it to the place in the cell where proteins are built.
DNA, RNA, Proteins (4 of 4) DNA to Proteins
DNA instructions are transmitted via RNA to construct proteins.
