Why is mitosis called duplication division

Um, but are are you care? Excels contained organelles, membrane bound organelles. Okay, so that those be some organelles but pro. Chaotic cells do not. Okay, So pro Kerry oats, I already have no Then rain bound organelles know.

So then so then it would be impossible for them to divide something they do not have some sort of eliminates. A leaving B is our choices. We just went through it. DNA duplication of sort of the whole point of cell division and buying a vision is that first step to get, you know, duplicated and to make two souls instead of one. So that checks out, segregating that, then duplicated chromosomes.

You can see in each of these pictures that they have been segregated to their respective sides in order to create, to sell, so that checks out on them in the division of cytoplasmic contents of sort of whatever goo is in here. And then in some cases and in our you care about excels that might contain organelles. Whatever these contents are, they get divided out. So it's that all checks out in our correct answer is B.

In chemistry and physics, an element is a substance that cannot be broken down into a simpler substance by chemical means. A pure element is a substance consisting of a single type of atom, with its chemical properties determined by that atom's atomic number, which is the number of protons in its nucleus.

Examples of elements include carbon, oxygen, aluminum, iron, gold, copper, mercury, and lead. In biology, the elements of life are the essential building blocks that make up living things. They are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. The first four of these are the most important, as they are used to construct the molecules that are necessary to make up living cells. These elements form the basic building blocks of the major macromolecules of life, including carbohydrates, lipids, nucleic acids and proteins.

Carbon is an important element for all living organisms, as it is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids.

Even the cell membranes are made of proteins. Andrew Hoyt , a professor of biology at Johns Hopkins University, "[though] many people use it to reflect the whole cell cycle that is used for cell duplication.

Like prokaryotes, single-celled eukaryotes, such as amoeba and yeast, also use cell division as a method of asexual reproduction. For complex multicellular eukaryotes like plants and animals, cell division is necessary for growth and the repair of damaged tissues. Eukaryotic cells can also undergo a specialized form of cell division called meiosis , which is necessary to produce reproductive cells like sperm cells, egg cells and spores.

The eukaryotic cell cycle is a series of well-defined and carefully timed events that allow a cell to grow and divide. G1 phase first gap phase : During this phase cells that are intended for mitosis, grow and carry out various metabolic activities. S phase synthesis phase : During this phase, the cell duplicates its DNA. Eukaryotic DNA is coiled around spherical histone proteins to create a rod-shaped structure called the chromosome.

During the S phase, each chromosome generates its copy, or sister chromatid. The two sister chromatids fuse together at a point called the centromere, and the complex resembles the shape of the letter "X.

G2 phase second gap phase : During this phase the cell continues to grow and generate proteins necessary for mitosis. M phase mitosis : Mitosis involves the segregation of the sister chromatids. A structure of protein filaments called the mitotic spindle hooks on to the centromere and begins to contract. This pulls the sister chromatids apart, slowly moving them to opposite poles of the cell. By the end of mitosis each pole of the cell has a complete set of chromosomes.

The nuclear membrane reforms, and the cell divides in half, creating two identical daughter cells. Chromosomes, become highly compacted during mitosis, and can be clearly seen as dense structures under the microscope. The resulting daughter cells can re-enter G1 phase only if they are destined to divide. Not all cells need to divide continuously. Anaphase : The paired chromosomes split at the centromere and the two halves migrate along the spindle fibers to opposite sides of the cell.

At the same time, the center of the cell begins to pinch. Telophase : Cell division occurs, and each is identical to the original. Cells return to Interphase and prepare for another round of division. You have authorized LearnCasting of your reading list in Scitable. Do you want to LearnCast this session?
