how many rounds of chromosome replication occur i the cell pirior to mitosis

One round of chromosome replication occurs in the cell during the S phase of the cell cycle. This results in each chromosome being duplicated, producing two identical DNA molecules called sister chromatids that are connected at the centromere.
DNA replication (chromosome replication) occurs only once before mitosis or meiosis.
Chromosome replication occurs during the S phase of the cell cycle. This is when DNA is synthesized to ensure that each daughter cell receives an identical copy of the genetic material during cell division.
DNA replication does not occur during meiosis. Meiosis is a specialized cell division process that involves two rounds of division to produce gametes with half the number of chromosomes as the parent cell. DNA replication happens during the interphase preceding meiosis.
The sites where DNA replication and separation occur are called the replication fork, which is formed during DNA replication when the double-stranded DNA is unwound, and the centromere, which is the region of a chromosome where sister chromatids are held together before separation during cell division.
DNA replication occurs during the S phase of the cell cycle.
