Final answer:
Nucleosomes are reformed during DNA replication to create a semi-conservative pattern with a 'patchwork' of old and new histones on the replicated DNA strands, ensuring tight organization of genetic material.
Step-by-step explanation:
The arrangement of nucleosomes after DNA replication is such that each daughter helix will contain one old strand, known as the template strand, and one newly synthesized strand. During DNA replication, the nucleosomes are disassembled ahead of the replication fork and then reassembled behind it. After replication, new histone proteins are incorporated into nucleosomes where the DNA has been replicated to form a sort of 'patchwork' of old and new nucleosomes on both strands. This process leads to the formation of a semi-conservative pattern of nucleosome assembly, ensuring that the genetic material remains compactly organized within the nucleus.
