What process is the fastest way to produce copies of dna?
larisa [96]

Control and experimental groups. They repeated their experiment several times and found the results were the same.
Ira Lisetskai [31]

Answer: Experience 1 is the one that has the greatest reliability.

Explanation:    Because of this potential variation, biological experiments need to have a large sample size and preferably be repeated several times.  With more samples and repeating the experiment more often, the probability of arriving at a wrong conclusion due to random variation is diminished. As experience 1 has had several repetitions, it is the experience with a more reliable result.
