Charges

Charge

1. (Science: physics) a fundamental physical attribute of a particle, which characterises the particles electromagnetic interaction with other particles and with electric and magnetic fields.

2. Storing energy in a battery or electric capacitor by running a current through it, opposite of discharge. (It is possible to charge most capacitors in either direction, but batteries charge one way, and discharge in the other.)

principle of error-prone PCR???

... of the Taq enzyme, such as combine with the regulatory subunit to control the activity, or something else. I mean, it is obviously not the charges, Mn2+ ions carry two positive as well as magesium; plus, Mn2+ ions have exactly the same function with Mg2+, to active enzymes. So I am thinking ...

Re: Are carbohydrates hydrophobic?

... "dipoles". This is due to the unbalanced charge of electrons in either part of the molecule. Remembering the principle that opposite charges are attracted, polar molecules have a weak attraction to other polar molecules. Water is a polar molecule, so a molecule of the same kind can ...

Finding the net charge of amino acid

list the prononizable groups, find their pKa and define their charge at desired pH. Then just sum the charges and you get your result.
