During electrophoresis, DNA molecules can easily be separated according to size because all DNA molecules have the same charge–m

ass ratio and the same shape (long rod). Would you expect RNA molecules to behave in the same manner as DNA during electrophoresis? Why or why not? Klug, William S.. Essentials of Genetics (p. 181). Pearson Education. Kindle Edition.

Answer:

To separate DNA using agarose gel electrophoresis, the DNA is loaded into pre-cast wells in the gel and a current applied.

Explanation:

The phosphate backbone of the DNA (and RNA) molecule is negatively charged, therefore when placed in an electric field, DNA fragments will migrate to the positively charged anode.

Which statements correct
sladkih [1.3K]
The correct answer is C. Here's why: 

Choice A is illogical. A single experiment does not confirm a theory as true. Multiple successful trials are needed for one to even consider a hypothesis to be accepted as a theory. 

Choice B is wrong. If a scientist finds a new way to test a hypothesis, experimental methods do change. Note that when there are additional ways to test a hypothesis, a scientist should test it with additional methods. 

Choice D is incorrect. If someone finds a way to test a new hypothesis, it would not be made into law since there is more information regarding the theory. This means that it would remain a theory until one can prove that it can't be tested using different methods.

Thus, all the fruits are sweet is also incorrect.
