WebThe unique structure of chromosomes keeps DNA tightly wound around spool-like proteins, called histones. Without such packaging, DNA molecules would be too long to fit inside cells! For example, if all of the DNA molecules in a single human cell were unwound from their histones and placed end-to-end, they would stretch 6 feet. WebThe hereditary material present inside the nucleus of a cell is called DNA. A typical higher eukaryotic cell contains 2m of DNA packed into a nucleus 10 micrometres in diameter. DNA is wrapped around basic histone proteins to form nucleosomes. These nucleosomes are further organized in the form of higher-order chromatin fibres.
