Elongation

Elongation

(Science: radiobiology) parameter indicating the degree to which the cross-section of a toroidal plasma is non-circular. Kappa=b/a, where b and a are the vertical and horizontal minor radii. As kappa is increased, the confinement in relation to the total current improves, but the plasma also becomes more and more unstable to vertical displacements. A circular plasma has kappa of 1, a common value for elongated plasmas is 1.7, and the absolute limit is probably around 2.

Question for experts: Helicases

... In a human/eukaryotic cell, there are multiple origins of DNA replication. Helicases are part of the whole DNA synthesis initiation and elongation process. Using ATP, they are able to pull the base pairs apart from the SSB proteins that has "straightened out" the DNA helix ...

Rate of Cell division in 4 regions of an onion root tip HELP

... look at four regions of an onion root tip and rank which will have the fastest to slowest cell division rate: Root Cap, Apical Meristem, Zone of Elongation, and the Zone of Maturation. So far, I've come up with this: (1 being the fastest) Root Cap...............4 Apical Meristem.......1 Zone ...

Re:

When turgor is reduced, the cell loses pressure and "deflates". This inhibits elongation and causes drooping. As to why growth rates fall to zero when cells are still turgid, I am sure that the cell being turgid doesn't mean it must grow. The turgor pressure ...

Turgor Question~

Why does the rate of cell elongation fall when turgor is reduced? Why does growth rate fall to zero when cells are still turgid?
