Mitosis and meiosis are forms of cell division that produce daughter cells containing genetic information from the parent cell. Mitosis is the division of the genetic material in the nucleus which is immediately followed by cytokinesis. On the other hand, meiosis occurs in sexually reproducing organisms and this type of cell division reduces the sets of chromosomes from two to one in gametes. Both mitosis and meiosis differ, however, both processes result in daughter cells forming. In the end of…

In cell theory, it is known that all cells arise from pre-existing living cells, through cell division. In cell division, this involves the supplying of identical genetic material from the parent cell, DNA and protein, to two daughter cells. It results in the daughter cells having the same number of chromosomes as the parent cell. We need cell division as it is used in reproduction of new species, growth and repair of damaged cells and tissues, and to reduce the cell size. Larger cells are…

caused by cellular division going wrong is Cancer and Tumors. (1)Disrupted passage through mitosis often leads to chromosome missegregation and the production of aneuploidy progeny. Aneuploidy has long been seen as a frequent characteristic of cancer cells. Also Aneuploidy has been seen as a frequent characteristic of tumorigenesis. Mitotic spindle assembly are drugs that are frequently used to treat various types of human tumors. These lead to chronic mitotic arrest if they are sustained from…

Observation of plant and animal cells through a light microscope. A cell is the most basic structure of any living organism and is capable of independently reproducing. Cells can be grouped into two categories, prokaryotic and eukaryotic. In a eukaryotic cell there are small organelles that carry out specific functions which can be compared to the organs in the human body. Some of these organelles include the nucleus, which holds the cells DNA, mitochondria, which produce ATP from glucose and…

All organisms are made of billions of cells, so cells can work together so that, in order to happen, the cell must be able to work. The cell must be able to maintain the balance to be able to work. As a result, through advances in scientists such as Peter Agry and Rodrik McKinnon, we are able to know how their work is. Through them, we discovered everything the cell needs to work. Through them, we discovered everything the cell needs to work: channels, gates, and fuses. The first aqueduct was…

mechanism of fusion of Egg and sperm in human? ANSWER: Gametogenesis is the formation of the sex cells in multicellular eukaryotes. The word Gameto mean the gametes and genesis for formation of . Gametes typically come in male (sperm) and female (eggs). In human , the process involves two specialized cell divisions. The purpose is to create a haploid cell able to be well-suited with another haploid cell. Sperms is formed by the process called spermatogenesis and eggs are formed by the process…

organelle come from and what does it do? The Mitochondria is the main source of energy or powerhouse in a cell. They are eukaryotic organelles that contain their own ribosomes and DNA and are surrounded by a double membrane. The more active a cell is, the more mitochondria are created. Depending on the structure and the shape of a cell, how much the mitochondria is constantly working to keep the cell functioning. Through cellular respiration this organelle produces the energy molecule, ATP.…

single-celled or multicellular organism that contains a membrane bound nucleus. A eukaryotic cell has a nucleus that entraps the DNA unlike the prokaryotic cell that lets it be free. A prokaryote is also known as bacteria. The DNA roams freely inside of the cell. Eukaryotic cells are large meanwhile prokaryotic cells are much smaller. There are many differences about the prokaryotes and eukaryotes cells. The DNA replication of a eukaryotic cell would be two chains held together by H bonds. The…

The development of advanced microscopes has enabled scientists to further their investigation on the criteria for life. As a result, biologists have been confronted with a baffling question: is there a size limit on life? If so, then just how small can something be before it can no longer be considered alive? Ever since the discovery of nano-sized particles called “nanobacteria” or “nanobes”, researchers have been scrambling to unravel and analyze the mysterious functions of these purported…

In the cell, you have a vast majority of organelles that perform as needed today to support it. These organelles must go by a certain way of processing each of its duties to keep it alive and healthy. It’s like an auto body factory. When one thing goes wrong it causes problems throughout the entire cell. This could cause major discrepancies and dysfunctions that would most likely cause the human body to shut down due to illness, sickness, disease or more severely, death. So it’s a must these…
