O
B. Nuclear transfer
O
C. Gel electrophoresis
O
D. Reverse transcriptase

Polymerase chain reaction is a method of preparing DNA for forensic analysis .

Explanation:

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.

The correct answer would be b. carbon dioxide (6 co2) + water (6 h2o) > glucose (c6h12o6/ sugar) + oxygen gas (6 o2)
