Chromosomes are replicated during DNA replication, which occurs during interphase.
interphase
They are replicated and then one set goes to each of the two new cells. The result is two cells with the same genetic material. This is distinct from meiosis, where the chromosomes replicate and then pair up, two cell divisions occur, and each of 4 daughter cells has 1/2 of the genetic material
they need to replicate their DNA so that each daugther cell gets the same amount of genetic material as the parent had..
The nucleus of a cell contains uncondensed chromosomes that have been duplicated. During the interphase of the cell cycle, before cell division, the chromosomes replicate and form sister chromatids that are still uncondensed and spread throughout the nucleus.
They replicate before meiosis begins, as it is the division phase. The chromosomes duplicate during interphase which is right before the beginning of meiosis. After going through meiosis I the chromosomes DO NOT duplicate nor do they cross over they simply continue on. Hope this helps. :)
crossing over
Chromosomes replicate in the Interphase part of Meiosis and throughout the whole process of Meiosis they only replicate once.
yes
Chromosomes replicate during cell division, so are present as a new cell forms.
chromosomes
Chromosomes replicate when DNA replicates during the S phase (synthesis) of of the cell cycle.
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 are replicated during DNA replication, which occurs during interphase.
No, after telophase (a.k.a. during interphase) the chromosomes entangle as they replicate however it does again become possible for individual chromosomes to be distinguished in prophase as the chromosomes begin to 'coil up' or condense.

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.

During interphase (more specifically the S-stage), the chromosomes are duplicated.
