WebDNA consists of two long polymers (called strands) that run in opposite directions and form the regular geometry of the double helix. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T). WebPolystyrene is an aromatic polymer, naturally transparent, made up of monomer styrene. Polyvinyl chloride (PVC) is a plastic polymer made of monomer vinyl chloride. The urea-formaldehyde resin is a non-transparent plastic obtained by heating formaldehyde and urea. Glyptal is made up of monomers ethylene glycol and phthalic acid. nova gold chains
