Describe what happens to the chromosomes in the following stage of Mitosis: Pro-metaphase. Describe what happens to the chromosomes in the following stage of Mitosis: Metaphase. Describe what happens to the chromosomes at each phase of mitosis: a. Prophase b. Prometaphase c. Me...
phase, mitosis, a process in which the sister chromatids separate and the nucleus divides, and cytokinesis, a process in which the cytoplasm divides, occur.Because a diploid cell contains two sets of chromosomes (two genomes, one from each parent), mitosis ensures that the DNA content of the...
To answer the question about the stage of mitosis in which chromosomes are arranged on the equator of the spindle, we can follow these steps:1. Understanding Mitosis: Mitosis is the process of cell division that results in two
During mitosis in eukaryotic cells, mechanical forces generated by the mitotic spindle pull the sister chromatids into the nascent daughter cells. How do mitotic chromosomes achieve the necessary mechanical stiffness and stability to maintain their integrity under these forces? Here we use optical tweeze...
The giant sex chromosomes can be easily identified in spermatogonial mitosis. The size of each chromosome, however, varies according to stage and fixation, so that it is useless to make absolute chromosome measurements. At mitotic metaphase, however, after acetic-alcohol fixation and Feulgen staining...
Chromosomes may exist as either duplicated or unduplicated—unduplicated chromosomes are single linear strands, whereas duplicated chromosomes (copied during synthesis phase) contain two copies joined by a centromere. Compaction of the duplicated chromosomes during mitosis and meiosis results in the classic ...
A : Anaphase-I is actual phase of reduction in number of chromosomes. R : Homologous chromosomes move to the opposite poles with both their chromatids. View Solution Name the stage of cell cycle at which one of the following events occur ...
Figure 1. Double-stranded DNA wraps around histone proteins to form nucleosomes that have the appearance of “beads on a string.” The nucleosomes are coiled into a 30-nm chromatin fiber. When a cell undergoes mitosis, the chromosomes condense even further. ...
In mouse spermatocytes, DSBs start to be made at leptonema, peak at zygonema, and decrease in number as cell progresses to pachynema. DSBs are distributed along the entire length of homologous autosomes (the homolo- gous), each formed by two sister chromatids. Conversely, given that mouse ...
