Before we answer your question, let’s review the steps followed by cells when they duplicate their DNA and divide, known as the cell division cycle or cell cycle. There are four stages in the eukaroytic cell cycle: Gap 1 (G1), DNA synthesis (S), Gap 2 (G2), and Mitosis (M)....
During mitosis, separation of the sister chromatids takes place in the process of cell division. This way the genetic material of the dividing cell is distributed. The distribution of chromosome occurs so that the identical character of the new cells can be maintained. The movement of the ...
d) Neither prokaryotes nor eukaryotes. Cell Division: The cell division is that process in which one parent cell will be divided into more than one daughter cells or new cells. The division of cells depends on prokaryotic and eu...
Which one is true of mitosis? AChromosomes must have centromeres to move to opposite poles BAll cells have a centrole, which anchors the spindle CChromosomes double during anaphase DFour identical daughter cells are formedSubmit Which of the following is not a stage of mitosis? AAnaphase BMeta...
Using site directed mutagenesis we recapitulate K129E expression in cultured human cells and assess its anti-apoptotic and mitotic activities. Results K129E retains its anti-apoptotic activity, but causes errors in mitosis and cytokinesis, which may be linked to its reduced affinity for borealin. ...
Intestinal epithelial cells line the luminal surface to establish the intestinal barrier, where the cells play essential roles in the digestion of food, absorption of nutrients and water, protection from microbial infections, and maintaining symbiotic in
In animals, mitosis occurs in body cells to produce growth and repair and maintain body tissues. Each daughter cell is a genetic replica of the original cell. Meiosis occurs in sexual reproduction to generate variablegametes, or eggs and sperm, which unite to form a new individual different fro...
degeneration of a seminiferous epithelium, which leads to male infertility [16–18]. In fact, primary spermatocytes are germ cells the most sensitive to heat stress [13]. Spermatocytes are very unique cells. They originate from spermatogonia and divide by meiosis giving haploid spermatids (that ...
