Before mitosis begins, the chromosomes in a cell replicate. This occurs during the S (synthesis) phase. Chromosomes need to replicate so that when the cell divides at the end of mitosis, the daughter cells each recieve a copy of the chromosomes.
Chromosomes replicate during the S phase of interphase, before meiosis begins. This ensures that each chromosome consists of two sister chromatids, which are then separated during the meiotic divisions to produce haploid cells.
Strictly speaking, the chromosomes are not copied during mitosis but already before cell division takes place. This phase is called INTERPHASE and is again divided into three phases, G1 (first gap), S (synthesis), and G2 (second gap). The replication of chromosomes only happens in the S phase.
When chromosomes replicate, they produce two identical sister chromatids that are connected at a region called the centromere. This process ensures that each daughter cell receives a complete set of genetic information during cell division.
the 2MAIN reasons they are resting from chromosomes touching one another to improve once you grow they enlarge there growth of development.
They replicate to form two identical daughter cells.

DNA replicates and forms tetrad—APEX.
mitosis is the process by which the DNA of a cell is copied, so chromosomes replicated throughout the process
Chromosomes replicate during cell division, so are present as a new cell forms.
yes, to a degree
Yes they have own DNA. So they replicate by their own
Chromosomes replicate when DNA replicates during the S phase (synthesis) of of the cell cycle.
