Basic structure of DNA showing spiral backbone and different nucleotides (Forluvoft via Wikimedia Commons). DNA itself is made up of smaller molecules called nucleotides that link up together to form two chains that are twisted together, a bit like the separate strands of a rope.But this twisted chain is not physically used to make, or build anything else other than more molecules of DNA. flat layer of cells forms human skin and a layer of cells folded to form a tube is how things like intestines or windpipes are formed. Cells, not DNA, are what act as building blocks. So, starting with DNA and finishing with a human: Genes are made of DNA.
