Explanation:
Answer:
The DNA will still move towards the positive electrode
Explanation:
Gel electrophoresis is a technique which is used by the molecular biologist to separate the fragments of DNA. In the procedure, a DNA sample of a particular concentration of DNA sample composed of a particular length of DNA is loaded into the samples.
The gel is usually set up with the positive electrode at the bottom and negative at the top which by mistake when placed at the bottom and positive at the top.
The DNA will still move from the DNA wells towards the positive side as the DNA moves in the gel as the DNA posses negative charge due to phosphate groups they have and therefore move towards the positive electrode (opposite charge always).
Thus, the DNA will still move towards the positive electrode is correct.
Answer:
Covalent bonds form when two atoms share valence electrons,
while Van der Waals forces cause an attraction between nonpolar
molecules
Explanation:
A covalent bond is said to be formed when two atoms of the same or different elements share electrons. In an ordinary covalent bond, each bonding atom contributes one valence electron while in a dative covalent bond only one of the bonding atoms provides the shared pair of electrons.
Van Der Waals forces is the major intermolecular interaction between non polar compounds. Van Der Waals forces " are caused by correlations in the fluctuating polarizations of nearby particles"(Wikipedia).

The folds in the photograph above were caused by compression at a thrust fault or a convergent plate boundary. Compression usually occurs where two tectonic plates converge or collide. The compression will cause rocks to fold upwards and this upward folding over time can lead to the formation of extensive fold mountains. Examples of fold mountains include the Alps, Andes, and the Himalayas.
