Where is DNA located?
DNA is located in the cells nucleus.
What is DNA made of?
The two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase either guanine, adenine, thymine, or cytosine as well as a monosaccharide sugar called deoxyribose and a phosphate group.
What is the DNA structure?
