Kinetochore. A kinetochore (/ kɪˈnɛtəkɔːr /, /- ˈniːtəkɔːr /) is a disc-shaped protein structure associated with duplicated chromatids in eukaryotic cells where the spindle fibers attach during cell division to pull sister chromatids apart. [1] The kinetochore assembles on the centromere and links the chromosome to microtubule ...
The kinesin-13 family, unlike other kinesins, has an internally positioned motor domain. They were initially named KIF-M because of the unique location of their catalytic core in the middle of the polypeptide between the N-terminal globular domain and the C-terminal stalk but they are truly special due to their versatile nature.
Mixing solvents creates cooling baths with variable freezing points. Temperatures between approximately −78 °C and −17 °C can be maintained by placing coolant into a mixture of ethylene glycol and ethanol, [1] while mixtures of methanol and water span the −128 °C to 0 °C temperature range.
That water, which is a couple of degrees above freezing, is getting trapped in parts of the glacier and forced further upstream. "It goes in every day, it gets squashed up under the glacier. It ...
List of. Freezing. episodes. Cover of the first DVD/Blu-ray volume of Freezing as released by Media Factory on March 30, 2011. Freezing is an anime series adapted from the manga of the same title written by Dall-Young Lim and illustrated by Kwang-Hyun Kim. Set in a slightly futuristic world, Earth has been invaded and is at war with aliens from ...
Freezing is a phase transition in which a liquid turns into a solid when its temperature is lowered below its freezing point. In accordance with the internationally established definition, freezing means the solidification phase change of a liquid or the liquid content of a substance, usually due to cooling. [ 1 ][ 2 ] For most substances, the ...
Cryogenic hardening. Cryogenic hardening is a cryogenic treatment process where the material is cooled to approximately −185 °C (−301 °F), usually using liquid nitrogen. It can have a profound effect on the mechanical properties of certain steels, provided their composition and prior heat treatment are such that they retain some austenite ...
Freezing point depression is responsible for keeping ice cream soft below 0°C. [1] Freezing-point depression is a drop in the maximum temperature at which a substance freezes, caused when a smaller amount of another, non- volatile substance is added. Examples include adding salt into water (used in ice cream makers and for de-icing roads ...
