– DNA is a polymer formed by linking many nucleotides together through phosphodiester bonds, creating a polynucleotide chain.
– Two such chains typically form a double helix structure, held together by hydrogen bonds between the bases.
– A nucleosome is a basic structural unit of DNA packaging in eukaryotes, consisting of a segment of DNA coiled around a core of histone proteins.
– A polypeptide is a linear organic polymer consisting of a large number of amino-acid residues bonded together in a chain, forming a protein.
