Final answer:
Fast PCR can be used in quantitative PCR for gene expression studies and in forensics for DNA profiling, aiding in criminal investigations and paternity testing.
Step-by-step explanation:
The potential applications for fast PCR (Polymerase Chain Reaction) are vast and significant in both research and practical applications. Two correct answers regarding the applications for fast PCR are in the field of quantitative PCR and forensics.
Quantitative PCR
Quantitative PCR is an advanced technique where initial cDNAs are amplified, which allows not only the detection of the presence of specific transcripts but also measures their relative amounts in a given sample. This method is crucial for studies involving differential gene expression and gene regulation. By employing fast PCR in this context, researchers can obtain real-time data and save valuable time during experiments.
Forensics
In the forensic sciences, PCR is utilized for DNA profiling, also known as genetic fingerprinting. This method helps identify individuals involved in crimes, or establish parent-child relationships in paternity testing. Fast PCR techniques enable quicker amplification of DNA, making it possible to obtain results much more rapidly than traditional methods, which is particularly beneficial in time-sensitive cases.
