What kind of bonds form between the negatively charged and positively charged poles of water molecules?
hydrogen bonds
Why the pH does affect the separation of amino acids by electrophoresis?
The separation of amino acids by electrophoresis is influenced by the pH because it affects the ionization state of the amino acids. At different pH levels, amino acids can exist in different forms (protonated or deprotonated), which affects their charge. Amino acids with different charges will migrate at different speeds during electrophoresis, leading to their separation.
Which features of DNA fragments are used to separate them in the process of gel electrophoresis?
The separation is caused by the electrical direct current applied to the gel. Those molecules charged negatively will tend to go to the anode (positive) and those negatively charged migrate to the cathode.
Is an insulator positively charged or negatively charged?
I believe they'd are positively charged.
Positive charged center of an atom?
The positively charged center of an atom is the nucleus. The nucleus contains the protons and the neutrons. The protons are positively charged and the neutrons have no charge, therefore the nucleus is positively charged.
Do positively charged DNA molecules flow to the negatively charged poles in the electrophoresis chamber?
Yes. Positive(+) goes to negative(-). During gel electrophoresis, the positively charged molecules move to the negative cathode, and vis versa the negatively charged molecules move towards the positive anode.
What is the primary attractive force among the polar molecules in liquid hydrogen chloride?
Polar molecules have a positively charged pole and a negatively charged pole. The positively charged pole of one molecule will attract the negatively charged pole of another molecule, in accordance with Coulomb's Law.
Phosphate groups interact with positively charged protein molecules called?
histones
What Condenses when negatively charged phosphate groups interact with positively charged protein molecules known as?
no one cares.
What kind of bonds form between the negatively charged and positively charged poles of water molecules?
hydrogen bonds
What charge does a molecule have?
Solute molecules can be positively charged, negatively charged, or neutral. For example, dissolving sodium chloride in water produces positively charged sodium cations and negatively charged chloride anions. Dissolving sucrose (table sugar) in water produces only dissolved neutral sucrose molecules.

What are three of charged biomolecules that electrophoresis is particularly useful in separating?
Electrophoresis is an analytical technique used to separate charged molecules based on the migration of molecules in an electric field. It is particularly useful in separating molecules such as: Deoxyribonucleic acid (DNA) Ribonucleic acid (RNA) ProteinsIt is commonly used as a diagnostic tool for detecting genetic mutations determining DNA sequencing and diagnosing certain diseases.
Once DNA has replicated it condenses when negatively charged phosphate groups interact with positively charged protein molecules known as?
Histones
How are molecules held together in an ionic solid?
electrostatic force of attraction between the positively charged cations and negatively charged anions
Can polar molecules have regions of charge?
Not only can they, they must. At least one positively charged region and at least one negatively charged region.
What is the coordinate bonding and what is the difference between it and the covalent bonding?
Covalent bonding involves two or more atoms sharing electrons. Coordinate covalent bonding is just an attraction that molecules have for other molecules based on the asymmetrical distribution of electrons in those molecules, creating negatively charged and positively charged regions (and hence, an attraction between the negatively charged regions of one molecule and the positively charged regions of another molecule).
