The goal of mitosis is to produce daughter cells that are genetically identical to their mothers, with not a single chromosome more or less. Meiosis, on the other hand, is used for just one purpose in the human body:the production of gametes—sex cells, or sperm and eggs. ...
separating the original parent cell into two daughter cells. Each of these daughter cells is a diploid cell with 46 chromosomes (now with just one chromatid each), just like the parent cell and all the other somatic cells in the human body. They’re also genetically identical to ...
Sera from dogs rendered aplastic by total-body irradiation stimulate human bone marrow megakaryocyte progenitors to form megakaryocyte colonies in plasma clot cultures. In this investigation, we evaluated the effects of varying concentrations of such sera on both the mitotic and endomitotic phases of hu...
Mitosis is when a cell divides to create two identical daughter cells.Mitosis occurs in somatic cells (all the cells that aren’t sex cells), and it’s a process critical for producing new cells and keeping the organism alive and healthy. Most cells in the human body only last a few day...
Mitosis and meiosis are important processes. \\ a) What does each accomplish; \\ b) where in the human body can each occur and \\ c) how do the cells produced compare in chromosome number to the parent cells? Summarize the biological significance of: a. Mitotic cell division b. Meiotic...
How does human life depend on mitosis? Mitosis affects life by directing the growth and repair of trillions of cells in the human body. Without mitosis, cell tissue would rapidly deteriorate and stop working properly.Which phase does mitosis and cytokinesis occur? M phase. During the mitotic (...

Functional Analysis of Human Microtubule-based Motor Proteins, the Kinesins and Dyneins, in Mitosis/Cytokinesis Using RNA Interference Microtubule (MT)-based motor proteins, kinesins and dyneins, play important roles in multiple cellular processes including cell division. In this study, we... Zhu,...
The function of mitosis is to divide a cell'snucleuswith its chromosomes into two daughter cell nuclei, each of which inherits the same number of chromosomes as the parent cell. Consider mitosis in human cells, each of which contains forty-six chromosomes. ...
