Hyperosmotic biology

WebIf a given solution has higher osmolarity compared to another solution, It is called hyperosmotic. When a solution has lower osmolarity than another solution, it is called hypoosmotic. Lastly, in case the two solutions have the same osmolarity, they are called isoosmotic. Bioninja.com WebThereby, we have functionally defined the smallest sequence able to confer hyperosmotic response on a downstream gene independent of other putative cis -elements, that is, a minimal essential osmotic response element (ORE). The sequence of the ORE is CGGAAAATCAC (C) (bp −1105/−1094). A 17-bp fragment (−1108/−1092) containing the …
