Answer:

A control in an experiment is a replica used to confirm that the results or changes in the dependent variable/s are caused by the independent variable values or treatments. There are different kinds of controls according to the experiment, for example,  no treatment can be applied, or for example in laboratory experiments, there are controls to check that the reactives function properly, making a replica with them but without the sample that is being measured.

If a DNA molecule has 24% adenine, what is the percentage of guanine in the same DNA molecule?
artcher [175]

Answer:

26%

Explanation:

Adenine pairs with thymine.

Guanine pairs with cytosine.

If 24% of the DNA molecule is adenine, that means that there is 24% thymine. This is because they pair together so they have to be equal. That is 48% of the DNA molecule. To find the percentage of guanine, we need to minus 48% from the total 100%.

100 - 48 = 52

Then divide by 2 because you have guanine AND cytosine.

52/2 = 26

Therefore, your final answer is 26% of guanine is in the DNA molecule.
