Why is mitosis necessary? What happens during interphase?

Answer 1

without mitosis we would still be a single cell zygote.

during interphase, the cell grows and produces the proteins necessary, and required for mitosis

Answer 2

Mitosis is necessary because cells are the building blocks of life and based on the cell theory, cells arise from cells via the process of mitosis. Therefore, if there was no mitosis , there would be no cell growth, and cell reproduction. Also, Mitosis has an importan phase known as interphase, during interphase DNA gets replicated, which means that an individuals genetic information is being passed onto another cell.

Answer 3

Going back to what the previous poster mentioned about cells being the building blocks of life, I disagree. Proteins are what make us up and therefore should get credit for being the building blocks of life. Proteins determine what phenotypes (appearance) and genotypes (DNA) we have. Amino acids are the building blocks of proteins. Every person has a unique sequence of amino acids and hence a unique protein profile. This is why everyone looks different. Our DNA contains the code for these unique strings of Amino Acids.

As for Mitosis:

I-P-M-A-T (use this as a mnemonic device) It will help you remember the stages.

(Interphase) -->Prophase -->Metaphase --> Annaphase-->Telophase.

These are the stages of Mitosis (somatic or body cell division). Mitosis is the process of body cell division resulting in 2 identical diploid cells. Diploid cells have the normal number of chromosomes (46) and haploid (sex) cells have half that number (23).

Some scholars do not include Interphase as part of Mitosis because the cell is not dividing.

Interphase is the most important part of cell-divison. It is in this stage that the Cell replicates all of its DNA. The cell spends most of its life in this stage. After replication the cell will enter into Mitosis and divide to make an exact copy of istelf.

Why is Mitosis necessary? Our bodies use Mitosis to heal themselves. One cell dies and another must take its place.

n=23 chromsomes
2n=46 chromosomes

In our sex cells a similar process is used, meiosis. This process in different in that the cell it creates is haploid not diploid. So it has half of the number of chromosomes than a body cell. Haploid is 23 and diploid is 46. A man's sperm cells have 23 chromosomes and a woman's eggs have 23. When they come toether in union they create a zygote, a fertilized egg which is diploid (2n=46). 46 is the normal number of chromosomes for humans.

What most people know is that males produce new sperm throughout their lives, however most people do not know that females are born with all of the eggs they will ever have for the rest of the lives. Females eggs are produced before birth and her eggs are the same age as she is. This is why it is imporant for females to have babies at a younger age because their eggs will be healthier and have a less chance for any genetic abnormalities to occur.

Cell division whether in body cells or gametes (sex cells), is necessary for body repair and reproduction.

Answer 4

Mitosis is cell division.No mitosis,then there is no cell production (you cant grow or regenerate from injury)
Interphase stage involves the growth of the freshly formed cell into a mature cell

Answer 5

Mitosis is the approach through which cells advance and restoration themselves. Cells bypass by IPMAT: Interphase, prophase, metaphase. anaphase, and telophase. figure (unique) cells, reflect their DNA, chop up and produce 2 alike/same daughter cells.

Answer 6

DNA replication happens during interphase. You just can't see it until the chromosomes condense during prophase.
