Humans have 23 pairs of chromosomes. During mitotic cell division, sister chromatids get separated to opposite sides of the cell (during anaphase). resulting in two sets of identical chromosomes. The cell divides, becoming two distinct cells, each with their own nucleus. Usually mitosis occurs wi...
A cell has 36 chromosomes. After it divides by mitosis, how many chromosomes will be in each cell? A cell has 36 chromosomes. After it divides by mitosis, how many chromosomes will there be in each cell? What a cell has one copy of each gene, it is called ___. Some...
Mitochondria are membranous organelles that produce most of the ___ for a cell, by breaking down food molecules and transferring the energy to the bonds of ___. Which of the following pairs is not correct? O mitochondria, the powerhouse of the cell O centrioles, form...
Two types of cell division are mitosis and meiosis. In meiosis, a cell splits to form new cells with half the number of chromosomes of the original cell, and produce gametes for sexual reproduction. In mitosis, a cell splits to form two daughter cells, which are genetically identical to e...
Mitosis What would happen if tight junctions and adherens junctions become non-functional in the epithelial cell layers of the intestines? ___ cells in simple columnar and pseudostratified columnar epithelia produce protective mucous coatings over ...
How does meiotic division occur? Meiosis is a process wherea single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. ... These four daughter cells only have half the number...
2.Analyze Statement ii: "LH triggers secretion of androgens from the Leydig cells." - LH does indeed stimulate the Leydig cells in males to produce androgens, primarily testosterone. This statement is correct. 3.Analyze Statement iii: "FSH stimulates the Sertoli cells which helps in spermiogenesi...
MVBs are generated by the progressive pinching-off of the endosomal limiting membrane to generate intraluminal nanovesicles that are subsequently stored in the lumen of endosomes. These MVBs which are loaded with intralu- minal nanovesicles can fuse with the plasma membrane to release the nanovesicles...
Skb1 has been suggested to regulate mitosis negatively and can be functionally replaced with its human homolog (Skb1Hs) in fission yeast (25). In this context, an interaction between Skb1Hs and NS3 may play a role in liver diseases caused by HCV. To investigate a function of Skb1Hs ...
Under such conditions, a given exposure of a DNA reactive chemical does not produce a linear or semi-linear increase in DNA lesions or in mutation frequency. However, even when these protective mechanisms are overwhelmed by the high exposures of genotoxic chemicals the biological effects of a ...
