mitotic chromosomes

[mī¦täd·ik ′krō·mə‚sōmz]
(cell and molecular biology)
Condensed, replicated chromosomes held together as sister chromatids by the centromere as part of the process ensuring accurate segregation and transmission of genetic material to the daughter cells during cell division.

We also uncovered an impact of Nesprin-2 on mitotic chromosomes that might be mediated by an interaction with the condensin core units SMC2/4.
The most frequent haploid number found in 50 metaphase I oocytes was n = 19 mitotic chromosomes (Fig.
However, it is not clear whether pRB directly interacts with HP1[alpha] to repress the expression of E2F-target genes because HP1[alpha] was found to be preferentially phosphorylated in the G2/M phase and to bind to histone H3 modified with both K9me3 and phosphorylated serine 10 in mitotic chromosomes [58].

During the mitotic phase of the cell cycle, a partial condensation of the DNA occurs in prophase, so that the mitotic chromosomes occupy a much smaller volume of the nucleus.
To obtain mitotic chromosomes in vitro, portions of anterior kidney were removed and transferred to RPMI medium (Cultilab) with about 50 [micro]L of 0.025% colchicine, followed by hypotonic treatment (KCL 0.075 M) for 20 minutes at 37[degrees]C and fixation in Carnoy's fixative (methanol: acetic acid 3 : 1) [20].
Using lentiviral particles also allows effective direct visualization of Nuclei, Nuclear Membrane, Mitotic Chromosomes and Interphase Chromatin, Endosome, Endoplasmic Reticulum, Microtubule, Mitochondria, Golgi, Lysosome, Plasma Membrane, Cytoplasm and Peroxisome in hard to transfect mammalian cells, stem cells and primary cells.
However, there are no available reports on karyotypes obtained from gill tissue of freshwater crayfish although the analysis of mitotic chromosomes provides a good tool to obtain the modal diploid chromosome number.
