The advantage to prokaryotes grouping related metabolic gene products into a single operon is they only needed one mRNA to create several gene products. This makes a prokaryote different to a eukaryote in terms of gene information processing. Prokaryotes have fewer genes. These genes are located in one chromosome only.
I’m sorry what are you actually asking
Answer:
The cells are identical because the DNA is copied during the S phase before cell division and then each resulting cell gets a matching copy of the chromosomes.
