The histones of DNA are synthesized in Correct Answer S phase

The histones of DNA are synthesized in the S phase.
The new histones are made in the cytoplasm during the S phase and are transported into the nucleus. It is deposited by chromatin assembly factors or histone chaperones on replicating DNA to form chromatin in a process known as chromatin assembly.
The old histones are disassembled from DNA, presumably shielded and chaperoned until they are reassembled into nucleosomes.
