in storage cells of the eutardigrade Richtersius coronifer (Richters, 1903), and analyse mitotic cells in relation to different body characteristics, including egg development stage, moulting, gut content, body length, number and size of oocytes, and shape and size of the storage cells. Mitos...
Somatic cells—that is, the cells in your body that aren’t sex cells—do this via a process called mitosis. New sex cells, or gametes, are produced via a different process, called meiosis. Today, we’re going to talk about both of these. How are they different? How are they similar?
Mast cell histamine, a local mitogen acting via H2-receptors in nearby tissue cells The tissue mast cell is the major storage site of histamine in the body. The present study is concerned with the effect of one histamine H1- and one histam... K Norrby - 《Virchows Archiv B》 被引量:...
Cell Division: Mitosis Chapter 8
Mitosis and cell division have been examined ultrastructurally in the vegetative cells of Hydrurus foetidus (Vill) Trev. and found to resemble that of Ochromonas in two important aspects. First, the rhizoplast acts as the spindle organizing body and second, the spindle elongates considerably durin...
How many sex cells are made from one body cell? How many chromosomes are in a human egg cell? If a cell contains six chromosomes in early interphase, how many chromosomes are present in prophase? What do chromosomes do only once in mitosis and meiosis?
in two. Plant cells have rigid cell walls that prevent this. Instead, they use two different approaches for cytokinesis. The plasma membrane and cell wall grow inward together, eventually separating the parent cell into two. Alternatively, the cell wall that will separate the two daughter cells ...
The genetic information contained on chromosomes is extremely important to the function of every cell in the body. As these cells divide it is very important to be sure that the genetic material-the chromosomes and genes-are carefully maintained. When a human cell with 46 chromosomes divides, th...
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. ...
In the fission yeast Schizosaccharomyces pombe, centromeres are clustered at the spindle-pole body (SPB) during the mitotic cell cycle; however, during... Y Chikashige,R Kurokawa,T Haraguchi,... - 《Genes to Cells》 被引量: 96发表: 2004年 加载更多...
