The development of a new experimental method is most likely to change a theory if it makes it possible to ?
a) analyze samples when they are frozen.
b) perform the experiment in a different lab.
c) obtain and analyze results more quickly.
d)study a larger sample size than before.

The correct answer is (d) )study a larger sample size than before.

The theory of the experiment depends on the sample size. If the sample size of the experiment is changed during the experimental procedure then the theory will also change. Taking a large sample size than before might require a different experimental procedure. To study a different sample size than before will increase or decrease the number of observations taken. The traits followed by the sample size may vary. This is the reason why a larger sample size than before may develop a new experimental method which will ultimately change the theory.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
