Definition of polarity : ...
Polarity
Nonpolar molecules diffuse faster through the lipid portion of the membranes.
Ions ...
polarity of characters -- The states of characters used in a cladistic analysis, either original or derived.
[edit] Polarity
The polarity of an actin filament can be determined by decorating the microfilament with myosin "S1" fragments, creating barbed (+) and pointed (-) ends on the filament.
polarity In systematics, the ordering of alternative states of a taxonomic character from ancestral to successively derived conditions in an evolutionary transformation series.
Changed polarity of the membrane, the action potential, results in propagation of the nerve impulse along the membrane. An action potential is a temporary reversal of the electrical potential along the membrane for a few milliseconds.
The polarity of water
Water has a simple molecular structure. It is composed of one oxygen atom and two hydrogen atoms. Each hydrogen atom is covalently bonded to the oxygen via a shared pair of electrons.
Having impaired polarity; applied to a compass needle. Like mad, like a mad person; in a furious manner; as, to run like mad. To run mad. To become wild with exci 6f7 tement.
There were what we call "maternal coordinate" genes, "Gap genes, "Pair-Rule" genes, "segment polarity" genes, and "homeotic" genes. They basically act in that kind of hierarchical order to set a pattern of the embryo.
This work deals with issues regarding the ion polarity combination, viz., positive oligonucleotides/negative charge transfer agent versus negative oligonucleotides/positive charge transfer agent.
patterning occurs progressively from the deployment of coarsely expressed gap genes to the more refined segment polarity genes (reviewed by Ingham, 1988)

As the action potential passes (B), the polarity is reversed. Then the outflow of K+ ions quickly restores normal polarity (C).
Due to this fact, each microfilament exhibits polarity, the two ends of the filament being distinctly different.
Define hydrogen bond and describe conditions under which hydrogen bonds form and cite one example.
Explain what is meant by the polarity of the water molecule, and how the polarity of water molecules allows them to interact with one another.
- The arrangement of complementary DNA strands, which run in different directions with respect to their 5' 3' polarity

Polar mutation
A mutation which affects not only the gene in which it is located but other genes located immediately downstream on the DNA molecule. See Rho dependent polarity .
