The process of mitosis has made more clear, thanks to recent research. A new study describes how Topo 2, an enzyme that disentangles DNA molecules and is essential for proper cell division.

First, however, the cells must duplicate their DNA. Mitosis is the process by which a cell segregates its duplicated DNA, ultimately dividing its nucleus into two. The mechanisms of cell division ...

In any case, as mitosis begins, a remarkable condensation process takes place, mediated in part by another member of the SMC family, condensin (Hirano, 2002; Hagstrom & Meyer, 2003). Like cohesin ...

It can be seen in the stages shown above that mitosis maintains the chromosome number or complement of a cell. Mitosis therefore maintains the chromosome complement and ensures that each daughter ...

Cell shape changes during mitosis Date: February 12, 2013 Source: Heidelberg, Universität Summary: Scientists have gained new insight into the process of mitosis in mammalian cells. Researchers ...

“During tissue formation, dynamic cell shape changes drive morphogenesis while asymmetric divisions create cellular diversity,” Herbert and Lovegrove said in a study recently published in Science.

Or do they want to make four “half-copies”, in preparation for sexual reproduction, where their genetic content will be made whole again by the process of fertilization? This choice is the choice ...

Their task was to work out which genes were vital for the process of mitosis, the immensely complicated operation where one cell divides into two. To do that, they systematically went through each ...

The complex, genetically determined process of mitosis in particular must take place very precisely: the entire genetic material, divided into chromosomes, must be segregated accurately into the ...

A single-celled organism called Chromosphaera perkinsii appears to possess a embryonic process similar to animal mitosis, even though the organism separated from animal’s evolutionary line a ...

Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to ...
