During which stage of a cell's cycle do the replicated chromosomes line up on the equator of the cell? What are all the stages of mitosis? What are the functions of each of the stages of mitosis? What stages are in meiosis that are not found in mitosis? What is the rel...
During metaphase, the cell's chromosomes align themselves in the middle of the cell through a type of cellular "tug of war." The chromosomes, which have been replicated and remain joined at a central point calledthe centromere, are called sister chromatids. In which phase of the cell cycle ...
How do zygotes form somatic cells? What is the result when a diploid cell undergoes meiosis? Does a mutation happen in a gamete or somatic cell? What would result if chromosomes did not replicate during interphase? When during the cell cycle are chromosomes visible?
The following are the steps of the lysogenic cycle:1) Viral genome enters cell2) Viral genome integrates into Host cell genome3) Host cell DNA Polymerase copies viral chromosomes4) cell divides, and virus chromosomes are transmitted to cell's daughter cells5)At any moment when the virus is ...
If the process of mitosis goes wrong, it usually happens in a middle phase of mitosis called metaphase, in which the chromosomes move to the center of the cell and align in an area called the metaphase plate. If they do not align correctly, they cannot move individually to opposite poles ...
To analyze the embryonic chromosomes, morulae were transferred to CZB containing 0.25 μg/ mL colcemid and incubated for 3 h and then transferred to a 1:1 mix- ture of 1% sodium citrate and 30% FBS hypotonic solution for 5–7 min at room temperature. After fixing, the cells were mounted...
Ceramide, the precursor of all complex sphingolipids, is a potent signaling molecule that mediates key events of cellular pathophysiology. In the nervous s
mRNA or protein alongside gRNAs targeting three loci (POLLED, H11, and ZFX) on different chromosomes. In vitrofertilized bovine embryos were injected 18 h post insemination. Letters that differ in the same column are significantly different (P < 0.05). SEM = standard error of the ...
