Basic structure: looks like a twisted ladder.

6 smaller molecules:

5 carbon sugar called deoxyribose,

phosphate molecule, 4

different nitrogen bases( adenine, thymine, and guanine).

There is 2 major steps. One of which is translation during which the information stored in DNA is transferred to a similar molecule called RNA. The 2nd is Translation, getting from a gene to a protein, takes place in the cytoplasm
