C. Experimental

Explanation - The cause and effect of a process would be studied in experimental investigations. However, in descriptive studies, relationship between the factors are not studies rather the detail of the process is studied. In comparative investigation, several factors are compared and its effects are analyzed.

In experimental investigations, experiments are carried out based on the hypothesis and then it is validated accordingly. Validation is a must to prove and disprove the hypothesis. Therefore, experimental data and hypothesis are related.

In STR profiling, PCR is used to obtain enough DNA to then detect the number of STRs at I specific loci.​
Licemer1 [7]

PCR technique is important in STR profiling in order to amplify and detect the number of Stars at a specific gene loci.

<h3>What is Short Tandem Repeat (STR) profiling?</h3>

Short Tandem Repeat profiling is a technique in molecular biology used to compare allele repeats known as STRs at specific loci in DNA between two or more samples.

The PCR (polymerase chain reaction) technique used in STR profiling involves making multiple copies is a particular segment of DNA in order to make enough quantities detectable in the analysis.

Therefore, PCR technique is important in STR profiling to detect the number of Stars at a specific gene loci.
