Answer:

i. Their size and charge

ii. This is due to the fact that they move when an electric current is applied.

Explanation:

i. The components of DNA are of particular use in gel electrophoresis are their size and charge.

ii. This is because since the charge to mass ratio is constant for the DNA molecules, electrophoresis separates the molecules based on their sizes only. This is determined by the distance the DNA molecule moves in the gel. The smaller molecules move a large distance while the larger molecules move a small distance. This can thus be used to identify the molecules.

Empirical evidence is obtained using our human senses, which statement
Inessa05 [86]

The statement “This type of evidence can be checked by others” best explains the importance of empirical evidence in science.

Explanation:

There are all kinds of evidence used in science, but empirical evidence is obtained as a result of <u>repeated experiments and observations</u>. This evidence is used to either support or argue against a scientific theory. Empirical evidence is the preferred evidence since this kind of evidence can be peer reviewed, i.e. reviewed by other scientists and/or researchers. In other words, the experiment can be redone, and the <u>evidence can be tested</u>.
