Aside from certain stages of sexual reproduction, all production of new cells is based on a process called the cell cycle in which nuclear division (mitosis) and cell division (cytokinesis) produce two identical daughter cells. Mitosis has four stages and relies heavily on cytoplasmic microtubules ...
The meaning of MITOSIS is a process that takes place in the nucleus of a dividing cell, involves typically a series of steps consisting of prophase, metaphase, anaphase, and telophase, and results in the formation of two new nuclei each having the same n
Abnormal mitosis is a hallmark of cancer cells in which regulatory mechanisms are perturbed leading to uncontrolled cell division with growth advantages of cells lacking tumor suppressor genes which results in characteristic tumor tissue. Several mitotic inhibitors have been used successfully as anticancer ...
In sexual reproduction, i.e., by the union of two gametes, the complex process of meiosis takes place, which produces cells that each contain only half the normal number of chromosomes. Direct cell division, in which the nucleus simply cleaves in two (sometimes but not always followed by ...
There are three major types of cell division, which are:Binary fission Mitosis MeiosisWhereas binary fission takes place in prokaryotic cells of simple single-celled organisms such as bacteria. Mitosis and meiosis take place in eukaryotic cells and are more advanced. ...
cell division in which mitosis occurs mitosis同义词 n. 间接核分裂,[细胞]有丝分裂 karyokinesis mitosis词源中文解释 "有核分裂的过程,细胞核染色质的分裂",1887年,德语中创造出这个词,源自希腊语 mitos "织物的线",一个不确定词源的词,加上现代拉丁语 -osis "行为,过程"。这个术语是由德国解剖学家瓦尔特...
Does mitosis occur in somatic cells? Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of...
Cytokinesis takes place in four stages:initiation, contraction, membrane insertion and completion. The events occurring within these stages differ in animal and plant cells. What are the main events of the second stage of mitosis? Prometaphaseis the second stage of mitosis. In prometaphase, chromos...
Before discussing the specifics about a particular step in the division of a cell's genetic material, it is useful to step back and review what takes place inside cells to even reach this point. DNA is one of two nucleic acids, the other being ribonucleic acid (RNA). Although DNA might...
Cell division is an essential process that takes place in every living cell. This process involves the division of a parent cell into two daughter cells. These daughter cells are structurally or genetically similar to the parent cell. There are two types of cell division that is mitosis and ...
