When do chromosomes replicate during meiosis?
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.
What specific role do chromosomes play in meiosis that distinguishes their function from their role in mitosis?
In meiosis, chromosomes play a unique role in creating genetic diversity by exchanging genetic material between homologous chromosomes during a process called crossing over. This distinguishes their function from mitosis, where chromosomes simply replicate and separate to produce identical daughter cells.
What do chromosomes do before mitosis?
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.
What phase of mitosis do the chromosomes replicate?
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.
What part of mitosis when the chromosomes replicate and become organized?
Chromosomes replicate and become organized during the interphase stage of the cell cycle, specifically during the S phase. This is when the cell's DNA is duplicated, resulting in two identical sister chromatids joined together at the centromere.

When do chromosomes replicate?
Chromosomes replicate during the S phase of the cell cycle, which occurs before cell division. During replication, each chromosome is copied to produce two identical sister chromatids connected at the centromere. This process ensures that each daughter cell receives a complete set of genetic information.
Why do chromosomes replicate?
They replicate to form two identical daughter cells.
The chromosomes do this in preparation for mitosis?
replicate or duplicate
In what cell phase does a cell replicate it's chromosomes?
The chromosmes beging te replicate in the S stage.
How many sections do human chromosomes replicate?
23
How many new cell must be produce each second to replace the entire RBC population?
2, because the chromosomes need to split before they can replace and replicate.
Do chromosomes replicate only during meiosis 1?
yes
What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
When do chromosomes (DNA) replicate?
mitosis is the process by which the DNA of a cell is copied, so chromosomes replicated throughout the process
Process during which chromosomes appear?
Chromosomes replicate during cell division, so are present as a new cell forms.
