Polymerase chain reaction is a method of preparing DNA for forensic analysis .
<u>Explanation:</u>
- In order to prepare DNA for the forensic analysis, it must be replicated in an amount that is easily detectable in any biomedical instrument for the analysis.  
- This polymerase chain reaction is a process that is helpful in preparing the DNA in huge amounts by amplifying it.  
- The mitochondrial DNA and nuclear DNA are the two types of DNA used in the forensic analysis.
