Chromatin. The major structures in DNA compaction: DNA, the nucleosome, the 11 nm beads on a string chromatin fibre and the metaphase chromosome. Chromatin is a complex of DNA and protein found in eukaryotic cells. [ 1] The primary function is to package long DNA molecules into more compact, denser structures.
Adenosine diphosphate ( ADP ), also known as adenosine pyrophosphate ( APP ), is an important organic compound in metabolism and is essential to the flow of energy in living cells. ADP consists of three important structural components: a sugar backbone attached to adenine and two phosphate groups bonded to the 5 carbon atom of ribose.
