With some chemical knowledge, you can fairly easily guess if a molecule will be polar or not. Each atom will have a different level of electronegativity, or ability to attract electrons. Actually calculating the polarity of a molecule precisely, however, requires determining the shape of the mole...

Sum the individual dipoles within the molecule to determine the overall dipole of the molecule. In a molecule like carbon dioxide, there are two dipoles that originate at the carbon atom and point towards the oxygen atom. These dipoles are oriented 180 degrees apart and are exactly the same ma...
The regulation of cellular shape and tension by curvatures at various length scales activates specific mechanotransduction pathways that synergistically determine downstream cellular functions. Changes in the balance of cellular forces required to adapt to curved environments can have dramatic consequences, prom...
the targetDNA is unzipped and hybridization of the RNA-DNA takes place. For both enzymesexists a crucial seed sequence next to the PAM to determine the specificity oftarget DNA binding. The seed sequence for Cas9 is about∼10 nt whereas for Cas12a it is about∼5–6 nt . When the hyb...
Here, we propose that microtubules determine cell polarity by modulating the pattern of adhesions that a cell develops with the underlying matrix, through focal inhibitions of contractility.Small JVGeiger BKaverina IBershadsky ANature reviews: molecular cell biology...
So, brain reorganization itself would not suffice to determine neuroplasticity without an amplified gain or loss of brain function, provided that the initial state of the brain is maintained and there is no change in the specific function of one region that is sufficient to reach and modify ...
inflammation. However, the THR effect involves the regulation of nutritional metabolism and needs further research to verify the research results of different animal models. In addition, further experiments need to determine how THR regulates the dynamic balance between intestinal flora, immune response ...
Determining Polarity The polarity of a bond is determined by a periodic concept called electronegativity. Electronegativity is an expression of an atom's tendency to attract electrons in a chemical bond. In order to determine the polarity of a bond, you must find the difference in the electronega...
between the two elements. If the electronegativities of both elements are very similar or the same, the bonds are non-polar. If this is the case, the entire molecule is also non-polar. If it has polar bonds, you must examine the molecule further to determine whether it is polar or ...
