WebThe DNA inside of a cell is organized so that it fits well within the small size of a cell. Its organization also facilitates the easy separation of the correct chromosomes during cell division. It also affect gene expression, transcription, and translation. 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.
