Mitosis Answers
What is the role of Mitosis after an egg has been fertilized?
Q. Can somebody help me with this question, I can't find the answer. I thought that only meiosis has a role in fertilized eggs, but the question asks about the role of Mitosis.

A. Mitosis is the process by which all cells divide. Many cells have a limited life span, and mitosis allows them to be renewed on a regular basis. Mitosis is also responsible for generating the many millions of cells that are needed for an embryo to develop into a fetus, an infant, and finally an adult.

How many chromosomes after mitosis in a haploids cell should i find ?
Q. Many protists, fungi, and plants have haploid cells that divide by mitosis. How many chromosomes would expect to find in the cells resulting from such a division? So after they divide the two new cells have the same exact amount. But why? Can someone explain me how lets say you have 6 chromosomes, after mitosis you have 6 in each new cell ?
Asked by th3instrument - Sun Jun 21 01:36:05 2009 - Biology - 3 Answers - Comments
A. Chromosomes in the organisms mentioned in the question are composed of two 'sister chromatids' or half chromosomes, connected by a 'centromere'. During Mitosis, every individual chromosome divides in half, down the centromere. So that each sister chromatid migrates to a new cell. This sister chromatid is replicated when it comes time for cell division again and it forms a chromosome complete with centromere and divides into two and so on... so since the individual chromosomes are split down the middle, the NUMBER of sister chromatids in each cell is the same. In contrast, during MEIOSIS, the NUMBER of chromosomes gets divided into two, because each parent must contribute one half of a PAIR of chromosomes (chromosomes come in pairs). So… [cont.]

Asked by getreal19783 - Sat Mar 6 13:00:35 2010 - Biology - 2 Answers - Comments
A. If a cell only underwent mitosis but not cytokinesis, there would just be one big cell. Inside of this cell, there would be the parts of what should have been, two separate and identical cells. The cell would just end up looking like the cell after telophase, because nothing else happens after that. To see a picture of what it would look like, just find a picture of the telophase stage of mitosis. Good luck and I hope I helped.

What is the differences between mitosis and meiosis?
Q. I have some clues about it, but not exactly sure. During mitosis, a parent cell divides into two exactly the same daughter cells, right? During meisosis, it reduces the chromosome number in half, but the daughter cells are not the same. But why isnt the daughter cells the same? Since my bio class start with plants, i am unclear on this mitosis and meiosis stuff (and i try to read the chapter about mitosis and meiosis, but got so confused about it...).
Asked by Travis - Mon Sep 4 01:07:21 2006 - Biology - 8 Answers - 1 Comments
A. Mitosis occurs and the daughter cells are the same as the parent cells. It contains a DIPLOID number of chromosomes. Meiosis is for the formation of gametes. As the chromosomes arrange at the center of the cell and is ready to split, the chromosomes exchange some genetic material. When they do split, it results in variation between the chromosomes due to the exchange of genetic material. It would then further split and result in a HAPLOID number of chromosomes. *diploid (2n) = twice the number of chromosomes in gametes of that organism *haploid (n) = number of chromosomes in gametes of that organism *gametes = ovum, sperm (animals) / pollen grains, ovum (plants)

How does mitosis originate in a human?
Q. I understand the processes of mitosis and meiosis. I just don't understand how humans are formed I guess. So a sperm and an egg are products of meiosis, and when they meet fertilization occurs. When does mitosis come into the picture? Does this single cell now undergo mitosis? Thanks in advance!

A. Quite right! When the sperm (spermatazoa) fertilises the egg (ovum) it forms a zygote with the full number of chromosomes (a diploid cell - 23 pairs). Once this fertilisation has occured, mitosis kicks in and the cell starts to divide, producing identical non-specialised (undifferentiated) cells, creating a ball of cells called an embryo. Eventually, genes in the embryo start to kick into gear and cells start tp differentiate (become specialised) - about day 5 - and then a cavity opens up between the cells turning the solid ball of cells into a hollow ball (like a football). This is known as a blastocyst; one section attached to the wall and turning into the placenta through differentiation, the majority of it's surface area turning into… [cont.]

The process is complicated, so state that plant cells do not cleave like animal cells and that they produce a cell plate from the Golgi apparatus. Also, plant cells don't have centromeres and instead use astral fibres. Before mitosis begins, chromosomes are replicated so that their numbers are doubled. After a cell undergoes mitosis, the two new cells are completely identical and have the same DNA.

Q. What is the main difference between binary fission and mitosis? A. There is no DNA replication in binary fission B. Two parents are required for mitotic reproduction C. Binary fission occurs in single-celled organisms only D. Mitosis takes place only in sexual reproduction I think the answer is B, but I'm not 100% sure.

What can you infer about the origins of mitosis about plant and animal cells?
Q. Mitosis is much the same in the animal cells and plant cells you have examined. What can you infer from this about the origins of mitosis?

en.wikipedia.org/wiki/Mitosis
Mitosis is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets, in two separate nuclei. It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two cells containing roughly equal shares of these cellular components. Mitosis and cytokinesis together define the mitotic (M) phase of the cell cycle—the division of the mother cell into two daughter cells, genetically identical to each other and to their parent cell. This accounts for approximately 10% of the cell cycle.
Noun
mitosis (plural mitoses)- (cytology) The division of a cell nucleus in which the genome is copied and separated into two identical halves. It is normally followed by cell division.
