To duplicate a chromosome, at least half of the nucleosomes on the daughter chromosomes must be newly synthesized. But histone proteins as new and old occupies strands differently as

#Unit 2. Cellular Organization

  1. New modified histones will tend to rebind one of the parental chromosomes at a position near their previous position on the parental chromosome

  2. Only new unmodified histones will tend to rebind one of the daughter chromosomes at a position near their previous position on the parental chromosome

  3. Old unmodified histones will tend to rebind one of the parental chromosomes at a position near their previous position on the parental chromosome

  4.  Old modified histones will tend to rebind one of the daughter chromosomes at a position near their previous position on the parental chromosome
