Meiosis Vs Mitosis

What are the most prominent differences between the processes of Meiosis and Mitosis, and how do they ultimately affect the end results? The most prominent difference between the process of Meiosis and Mitosis is the number of divisions involved: Mitosis only has one major division whilst Meiosis has two. The divisions affect the overall outcome because they have a direct correlation to the number of daughter cells produced-- which is to say, the more divisions a cell undergoes, the more daughter cells it produces. In this specific context, Mitosis typically produces two diploid cells with exact replicas of the parent cell’s DNA, and Meiosis produces haploid daughter cells with half the DNA of the parent cell’s.
What are the major divisions
This prepares the parent cell for the cleavage furrow, and eventual division.
Explain the process of Telophase.
Telophase is considered the final stage of mitosis. The cleavage furrow is set and the daughter cells are well-formed, so much so that each has a forming nuclear envelope around their genetic material.
Explain the process of Cytokinesis.
Cytokinesis is the ultimate division: the daughter cells finally split from each other into their own cells, each with genetic material that will allow them to perform cellular functions and grow.
What is a cleavage furrow, and is it a vital part of the cell cycle?
The cleavage furrow is referred to as a “purse string” that is drawn tight around the cell in order to induce division. It is a vital part of the cell cycle, specifically cytokinesis, because it is a major factor in the division of the parent cell into two daughter cells; without it, the parent cell would remain a single entity and lack the ability to divide.
Why do mitosis and meiosis occur in the
Without division, a cell would continue to grow without organization and eventually be unable to keep up with its needs.
How long, on average, does mitosis occur? Does the time matter?
Mitosis, for most eukaryotic cells, averages 20 minutes from start to end. The time does matter, because the efficiency of reproduction directly affects growth in plants and animals, meaning that the more cells reproduce, the quicker an organism grows.
Why does synapsis of homologous chromosomes only happen in meiosis?
Synapsis is the alignment of the genes on the chromatids of homologous chromosomes. Therefore, it only happens in meiosis because the haploid daughter cells each are given half of the parent cell’s DNA, unlike in mitosis, where each daughter cell is given an exact copy.
What is the metaphase plate and what purpose does it serve?
The metaphase plate is an imaginary plane within the cell, on which the chromosomes line up. Once they are lined up, spindle fibers are able to attach themselves to the centromeres and pull chromosomes to opposite poles, facilitating the division of DNA through cytokinesis.
What is the chiasma, and in which process is it found: mitosis or
