If the DNA from all 46 chromosomes in a typical diploid human nucleated cell were laid end to end, its combined length would be about two meters. Inside the cell, DNA is not a loose thread: it wraps around histone proteins to form nucleosomes and is further organized into chromatin and chromosomes. This packaging also allows DNA to be accessed for copying and gene expression.
