Phases

phase separation

(Science: chemistry) The separation of fluid phases that contain different concentrations of common components.

Occurs with partially miscible solvents used in many biochemical separation methods. Also temperature dependent phase separation occurs with some detergent solutions. With reference to membranes means the segregation of lipid components into domains that have different chemical composition.

Re: Cancer and Cell cycle - cyclins/cdk/mutated genes?

... affects the cell cycle it will be that it has mutated the proteins that keep it tightly regulated. Whether or not it speeds up the individual cell phases of the cycle I do not know, but if the regulatory proteins are mutated to be permanently activated/"on" then it will proceed thru the ...

Cancer and Cell cycle - cyclins/cdk/mutated genes?

General questions about how cancer affects the cell cycle... 1) Does cancer actually speed up the individual phases of mitosis (prophase, metaphase, anaphase, telophase) ... ie metaphase occurs 100x sooner following prophase in a cancer cell compared to a normal cell? or does ...

Enquiry about interpreting the FACS result

... say, G1 in interphase in the cell cycle. If the populations then look uniform, the dual population was most likely caused by different cell cycle phases (e.g. late mitotic cells that are bigger than normal cells). Alternatively you can keep your cells a few days without growth-promoting substances ...

Can any one clarify my question with DNA
