What is the importance of DNA replication in the cell reproduction?
DNA replication is significant in the reproduction of cells through the mechanisms of mitosis and meiosis. The DNA replicates so that there will be an extra DNA when the cell multiplies, allowing the "daughters" the chance to reproduce.

The number of chromosomes in a gamete of an organism is its what?
D. Be produced by meiosis
When a cell undergoes meiosis one cell becomes four what also occur from meiosis?
B. Cells must divide twice before meiosis is complete C. Cells produced after meiosis I are diploid. D. Cells produced after meiosis II are haploid.
What is the role of the equator in mitosis?
to attach itself to d chromosomes
How many eggs form as a result of meiosis?
Female meiosis is a lifelong process that begins at puberty and ends at menopause. The ages of puberty and menopause vary from female to female, hence the total number of eggs formed varies. More consistently, as any woman could tell you, one egg is formed every month by meiosis.
What result in two identical daughter cells?
Mitosis! :D Meiosis results in 4 sex cells. :3
Sex cells divide using the process called?
The production of sex cells is called "gametogenesis." This makes sense since a gamete is a reproductive cell and "genesis" means creation or beginning. If the sex cells being produced are sperm the process is called "spermatogenesis" and if the sex cells being produced are eggs it is called "oogenisis."
In which phase of mitosis does cytokinesis take place?
Telophase: Cytokinesis occurs during meiosis and mitosis and is the stage at which the cytoplasm and surface membrane of the two cells divides, and the cells are distinguishable as separate.As a stage of the cell cycle, cytokinesis occurs at the end of mitosis/meiosis, and as a phase of mitosis/meiosis, it is itself a phase.
What are the similarities and differences between mitosis and meiosis with respect to function location in the organism and the chromosome number haploid or diploid of the daughter cells produced?
Mitosis produces two Diploid Cells while Meiosis produces four haploid cells. The purpose of Mitosis produces new body cells and does not allow for genetic variation, while meiosis allows genetic variation through multiple processes. Meiosis produces sex cells (sperm) , which are key in reproduction of multi-cellular organisms. Each new cell contains half of the number of chromosomes. Meiosis has 2 cellular divisions, while mitosis only has one. They are both necessary to support life, and they both produce Diploid cells in the first division. Also, from a similar topic in Yahoo Answers (Which has a much better explanation) : Mitosis is a type of cell division to produce 2 X genetically identical diploid (2n) cells for growth and repair. Mitosis occcurs in somatic cells (normal body cells. Prior to mitotic division DNA is replicated to produce two identical chromatids attached by a centromere. This is essential so that each new daughter cell formed receives one copy of each chromosome. (One division) Meiosis only occurs in the sex organs to produce 4 X haploid (n), genetically different, gametes for sexual reproduction. Meiosis consists of two divisions: Meiosis I halves the number of chromosomes to give 2 X haploid cells. Meiosis II doubles the number of cells to give 4 X haploid gametes. Two processes during meiosis I increase variation . In prophase I homomolgous chromosomes cross over at points called chiasmata and exchange genetic material. In metaphase I the chromosomes line up along the equator in pairs. This is called random assortment where maternal and paternal chromosomes are arranged at random. Both of these increase variation to produce four genetically different gametes at the end of meiosis II DNA replication only occurs once, before Meoisis I.
What does iPMAT mean?
Interphase, Prophase, Metaphase, Anaphase, and Telophase (stages for mitosis) :D Interphase, Prophase, Metaphase, Anaphase, and Telophase (stages for mitosis) :D
In animals somatic cells are produced by mitosis and answer here are produced by meiosis. a. gametes b. clones c. zygotes d. spores e. diploid cells?
Gametes are your haploid sex cells which are formed by meiosis. Gametes combined to form a zygote which is a diploid cell. Spores are haploid plant sex cells. Clones doesn`t even make sense ...

During what cell cycle phase is the spindle formed?
The spindle forms during prophase of mitosis or meiosis. The spindle is made up of protein fibers, which are microtubules of the cytoskeleton.
What would happen if mitosis stopped working?
we;d die
What is the role of the equator in mitosis?
to attach itself to d chromosomes
