Meiosis is not cell replication; that process is called mitosis (the identical replication of cells).
Meiosis is the process of sexual replication at the cellular level. While additional cells are created, they are not replicated. Instead, through the process of fertilization, a gamete - a cell composed of the hereditary information of two parent cells - is created. Through this process, a species generates genetic diversity.
Meiosis consists of 8 main phases: Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, and Telephase II. This process can be summarized as follows:
- During interphase, the chromosomes replicate. Each chromosome consists of two identical chromatids.
- At the start of meiosis I, homologous chromosomes pair up. The homologous chromosomes exchange genetic material with each other in a process termed crossing over.
- During meiosis I, the homologous pairs of chromosomes separate. One of each pair goes to each of the two daughter cells. The result is two haploid daughter cells.
- In meiosis II, the two daughter nuclei divide again. This time the chromatids of each chromosome separate. Meiosis II is similar to mitosis. The end result is four haploid cells.

What two cell division process use DNA replication?
The two cell division processes that use DNA replication are mitosis and meiosis. Mitosis is a type of cell division that results in two identical daughter cells that are genetically identical to the parent cell. Meiosis is a type of cell division that produces four daughter cells, each with half the number of chromosomes as the parent cell, and is involved in the production of gametes for sexual reproduction.
When does DNA replecation occur in meiosis?
DNA replication occurs during the S phase of interphase, which happens before meiosis I in the cell cycle. This ensures that each chromosome consists of two sister chromatids before the start of the meiotic divisions.
What is the term process of chromosomal DNA being duplicated?
Chromosomes duplicate in a process called mitosis.
Does DNA replication happen before or during Meiosis?
It happens during interphase of the cell cycle.
What process is used to produce sperm cells and egg cells?
The cell is produced in the Testes, in a process called Meiosis what is meiosis?
What is the process by which a cell makes a copy in meiosis?
Before meiosis begins, the cell copies its DNA in the process of DNA replication.
What process is preceded by the replication DNA?
The process that is preceded by DNA replication is cell division, specifically mitosis or meiosis. DNA replication ensures that each daughter cell receives a complete set of genetic information.
What process Are Gametes produced?
Gametes are produced through a process called meiosis, which involves two rounds of cell division. During meiosis, a germ cell undergoes DNA replication and genetic recombination to produce haploid gametes with half the number of chromosomes as the original cell. This process ensures genetic diversity in offspring.
DNA replication occurs?
The Replication of DNA does occur before the cell can divide.
Which does not occur during meiosis?
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.
In which stage of the cell cycle, mitosis or meiosis, does DNA replication occur?
DNA replication occurs in the S phase of the cell cycle, which is part of both mitosis and meiosis.
How many different ways are there for a cell to replicate?
Cell replication can occur through mitosis, meiosis, or binary fission, depending on the cell type and purpose. Each process involves specific steps to ensure accurate duplication of genetic material and division of the cell. Ultimately, the diversity of cell replication methods reflects the complexity and adaptability of living organisms.

The process that makes an exact copy of a cell's DNA is called?
The process that makes an exact copy of a cell's DNA is called DNA replication. During replication, the DNA double helix unwinds and each strand serves as a template for the synthesis of a new complementary strand, resulting in two identical DNA molecules.
Can an organism live a health life without any cell undergoing meiosis?
Meiosis is the replication of sex cells, so if an organism doesn't want to reproduce offspring, then they can live healthily without undergoing the process of meiosis. However, mitosis is the replication of every other cell in the body, assisting with growth and repair so no organism can live a healthy life without undergoing the process of mitosis.
When does DNA replecation occur in meiosis?
DNA replication occurs during the S phase of interphase, which happens before meiosis I in the cell cycle. This ensures that each chromosome consists of two sister chromatids before the start of the meiotic divisions.
