How a cell divides to make two genetically identical cells. Prophase, metaphase, anaphase, and telophase.

Direct link to Ahmed Muqtder's post “Asexual reproduction = fo...” Asexual reproduction = formation of one or multiple genetically identical individuals from one parent. Mitosis = duplication of the cell's chromosomes, after which two identical cells are formed, so not whole individuals. ... Asexual reproduction involves only one parent. All the offspring are identical to the parent (4 votes) Jamilah S. T. 9 years agoPosted 9 years ago. Direct link to Jamilah S. T.'s post “In the last paragraph, it...” In the last paragraph, it's said that you end up with 2 "new" cells, but wouldn't one of those new cells be the parent cells? The diagram could be read like that too. • (40 votes) Yasmeen.Mufti 9 years agoPosted 9 years ago. Direct link to Yasmeen.Mufti's post “The 'original' cell, befo...” The 'original' cell, before it divides, is called the parent cell. Both new cells are called daughter cells. (The 'parent' cell ceases to exist after mitosis.) (33 votes) Yara G 9 years agoPosted 9 years ago.

Direct link to Julia Nilsson's post “In plant cells, the first...” In plant cells, the first part of mitosis is the same as in animal cells. (Interphase, Prophase, Metaphase, Anaphase, Telophase). Then, where an animal cell would go through cytokineses, a plant cell simply creates a new cell plate in the middle, creating two new cells. The cell plate later changes to a cell wall once the division is complete. (22 votes) Grishma Patil 9 years agoPosted 9 years ago.

Direct link to RowanH's post “The nucleolus is a region...” The nucleolus is a region in the nucleus where the genes encoding rRNA (for ribosomes) are found. In fact, the structure of the nucleolus relies on transcription of these genes. The rRNA genes are found on several chromosomes. During mitosis, the chromosomes each condense and separate, so clearly the nucleolus can't stay around the whole time during mitosis. I would guess that there is more control to its disassembly though than just the surrounding DNA being pulled away during condensation. (11 votes) mario.medrano92889 9 years agoPosted 9 years ago.

Direct link to emilyabrash's post “Yes, it is, you are exact...” Yes, it is, you are exactly right! Actin is an important part of the cell's "skeleton" and is used in many different cellular processes that need strong fibers. (20 votes) Aayush Shah 9 years agoPosted 9 years ago.

Examples? • (12 votes) Mark 9 years agoPosted 9 years ago. Direct link to Mark 's post “Yes motor proteins are es...” Yes motor proteins are essential proteins for all organisms - they have lots of important roles such as muscle contraction, transporting cargo around the cell and cell motility (e.g. enabling sperm to swim!). Nice question. https://en.wikipedia.org/wiki/Motor_protein (7 votes) dmocnik 9 years agoPosted 9 years ago. Direct link to dmocnik's post “How does the cell "know "...” How does the cell "know " to carry out Mitosis ? Is it directed by its DNA ? • (7 votes) George Seese 8 years agoPosted 8 years ago. Direct link to George Seese's post “The details of what cause...” The details of what causes this or that to happen is probably still being studied. Whereas we know how proteins are made from genes, many questions remain in other areas like mitosis. Like, how does the mitotic spindle system know that all chromosomes have been connected?

Direct link to tyersome's post “Good question!Under nor...” Good question! Under normal circ*mstances this is relatively rare, but if the sister chromatids from a chromosome fail to separate during anaphase they will typically both end up in one daughter cell. This mistake is known as mitotic nondisjunction and results in the daughter cells being aneuploid (having an incorrect set of chromosomes). Aneuploidy is often associated with severe developmental defects, cancer, or death.

Direct link to KMP3344's post “Mitosis does not produce ...” Mitosis does not produce poop, that is just a cellular process. However, mitosis does produce the cells that make poop, so in a way mitosis actually does make poop, just indirectly. (2 votes)Want to join the conversation?
