Statement I is true, but Statement II is false.
DNA fingerprinting is a valid forensic technique, but the method of analysis involves DNA-specific techniques, not RNA analysis methods.
Statement I is true; DNA fingerprinting (or profiling) is widely used in forensic investigations for identification purposes, such as matching samples from a crime scene to a suspect. Statement II is false; Northern Blotting is a technique used to detect specific sequences of *RNA*. DNA fingerprinting techniques involve analyzing DNA, using methods such as Southern Blotting (historically) or more commonly PCR amplification of variable regions (like STRs) followed by electrophoresis or sequencing.
