What stage of mitosis does replication happen in?
Replication does not take place during mitosis. It takes place before meiosis begins.
When does replication happen during mitosis or meiosis?
Replication occurs during the S phase of the cell cycle before both mitosis and meiosis. In mitosis, the replicated DNA is separated into two identical daughter cells. In meiosis, the replicated DNA is separated into four haploid daughter cells with genetic variation.
What must happen before meiosis begins?
A duplication of the chromosomes is what must happen before meiosis can begin.
What must happen before meisois can begin?
Before meiosis can begin, the cell must undergo a process called interphase, specifically during the S phase, where DNA replication occurs. This ensures that each chromosome is duplicated, resulting in sister chromatids. Additionally, the cell must prepare by accumulating the necessary proteins and organelles required for the meiotic process. Once these conditions are met, the cell can enter meiosis, starting with prophase I.
What happens during the first division of meiosis that does not happen in meiosis?
In Meiosis I: Separates homologous chromosomes In Meiosis II: Separates sister chromatids

What is copied before mitosis begins?
DNA, the genetic material, of course. Also mitochondria and chloroplasts need to divide. This is the process of mitosis where two daughter cells are produced and both will need the complete complement of genetic material; DNA.
What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
What must happen before meiosis or mitosis can take place?
The cell must undergo DNA replication to ensure that each daughter cell will receive a complete set of chromosomes during meiosis or mitosis. This step is crucial for the accurate distribution of genetic material to the daughter cells.
What must happen before meiosis happen?
Before Meiosis 2, the cell must first go through Meiosis 1. This is when the cell splits into two cells, each with two chromosomes.
How many times does DNA replicate in mitosis?
DNA replicates only once during the S phase of the cell cycle before mitosis begins. This ensures that each daughter cell receives a complete set of genetic material that is identical to the parent cell.
What mutations occur during cell division?
During cell division, mutations can occur due to errors in DNA replication, exposure to mutagens (such as chemicals or radiation), or spontaneous molecular changes. These mutations can lead to changes in the genetic information of the daughter cells, potentially causing genetic disorders or contributing to the development of cancer.

What happen to the organism when something goes wrong during meiosis?
it can go really weird
