Here are the essential concepts you must grasp in order to answer the question correctly.
Polymerase Chain Reaction (PCR)
Polymerase Chain Reaction (PCR) is a molecular biology technique used to amplify specific DNA sequences, making millions of copies from a small sample. This is particularly useful when working with degraded or limited DNA, such as that from ancient or preserved specimens. By using specific primers that bind to the target DNA, PCR enables researchers to generate sufficient quantities for further analysis.

DNA Amplification
DNA amplification refers to the process of increasing the number of copies of a specific DNA segment. Techniques like PCR are essential in genetic research, forensic analysis, and paleogenomics, as they allow scientists to work with minute amounts of DNA. Amplification is crucial for obtaining enough material for sequencing or other genetic tests, especially when dealing with ancient or fragmented samples.

Molecular Probes
Molecular probes are short strands of nucleic acids that can bind to specific sequences of DNA or RNA, allowing for the detection and quantification of these sequences. While they are useful for identifying specific genes or mutations, they do not increase the amount of DNA available for testing. Instead, they are typically used after amplification techniques like PCR to analyze the amplified DNA.
