In telophase, the chromosomes uncoil, the nuclear membrane reappears and the cell splits into two daughter cells, each having 46 chromosomes. The daughter cells should have the same genetic information (DNA) as the parent cell. All cells...
How does the number of chromosomes in a parent cell compare with the number of chromosomes in a daughter cell? Why is this important? What is the difference between T cell and B cell's function in attacking antigen? Explain the relationship between gene expression, protein, environme...
DNAis needed by a cell in order to divide into two daughter cells bycell division. DNA is duplicated byDNA replication. So, there should be a special mechanism in order to replicate the highly wound spiraled DNA. Topoisomerase is anenzymethat can cut DNA at a particular point and unravels ...
epigenetics is the term used to describe inheritance by mechanisms other than through the DNA sequence of genes. It can apply to characteristics passed from a cell to its daughter cells in cell division and to traits of a whole organism. It works through chemical tags added to chromosomes that...
(Synthesis) stage DNA is duplicated. “G2” stage is constituted of further cell growth by multiplying cell organelles. During the mitotic phase, the chromosomes separate. And finally, in the cytokinesis phase, the chromosomes and cytoplasm separate into two new daughter cells where it completes ...
combination of the parents), produces reproductive cells—called gametes—that unite to form an offspring. Examples of gametes are sperm, egg, pollen, and ovules. Gametes are haploid cells. This means they contain only half the number of chromosomes- (strand of DNA) found in other cells of ...
calcium phosphate nanoparticles and a liposomal transfection agent S Chernousova and M Epple The processing of DNA (for transfection) and short interfering RNA (siRNA; for gene silencing), introduced into HeLa cells by triple- shell calcium phosphate nanoparticles, was followed by live-cell imaging....
Tumor suppressor gene tells the when to die, repair the mistakes made in the DNA, and slow down cell division. If a tumor suppressor gene gets mutated the cells will grow out of control with nothing to stop them. The mutation can be caused when this gene isn’t activated. Two common ex...
The processing of DNA (for transfection) and short interfering RNA (siRNA; for gene silencing), introduced into HeLa cells by triple-shell calcium phosphate nanoparticles, was followed by live-cell imaging. For comparison, the commercial liposomal transf
cells proliferate, the CFSE present in the parent cells is effectively halved in each of the daughter cells, so each new generation is half as bright as its parent. Analysis by flow cytometry then reveals clear population generations based on diminishing fluorescence intensity, as well as the ...
