In metaphase, the chromosomes line up along the metaphase plate. Then the metaphase checkpoint ensures that the mitotic spindle has formed correctly and the chromosomes are properly aligned on the metaphase plate. What is the metaphase of a cell? Metaphase represents one of the steps of mitosis,...
The stage of cell division in which the spindle forms and chromosomes line up along the center of the cell. In mitosis, metaphase is preceded by prophase and followed by anaphase. See more atmeiosis,mitosis. The American Heritage® Student Science Dictionary, Second Edition. Copyright © 2014...
Chromosomes are nothing more than distinct pieces of chromatin. Humans have 23 different chromosomes, 22 that are numbered and one that is a sex chromosome, either X or Y. Every somatic cell in your body contains a pair of each chromosome, one from your mother and one from your father. Pa...
intensity increase of thephenylalanineline at 1004 cm−1could have the same cause, indicating a change in the microenvironment of thephenylrings. However, it cannot be excluded that during the fixation and squashing of the cells the chromosomes are contaminated with, for example,cytoplasmic ...
Metaphase begins when the chromosomes line up in a plane midway between the two poles (Walker, 1907; Bajer, 1958b; see Figs. 19.6 and 19.7). The formation of a metaphase plate is not essential for mitosis, and in cells, particularly those of the fungi, the chromosomes do not line up ...
in biology, the stage in mitosis and meiosis in which the duplicated chromosomes of the dividing cell line up along the equatorial plane of the spindle.metaphase同义词 n. (细胞分裂的)[细胞]中期 medium term adj. [细胞]中期的;转位期的 medium-termmetaphase...
In certain types of cells, chromosomes do not line up at the metaphase plate and instead move back and forth between the poles randomly, only roughly lining up along the middleline. 展开 关键词:Mitosis Eukaryote Cell chromosome DNA 出版时间: 2010-09-20 ...
This structure is employed to make up the higher-order chromatin fibre with a 30-nm diameter. Because 30-nm fibrous structures have been repeatedly observed under scanning electron microscopy (SEM) at the surface of metaphase chromosomes3, they have been referred to as the basic chromatin fibre....
Telophase is the last phase of mitosis.Telophase is when the newly separated daughter chromosomes get their own individual nuclear membranes and identical sets of chromosomes. Toward the end of anaphase, the microtubules began pushing against each other and causing the cell to elongate. Those polar ...
