Real-Time PCR
Continuing Education Credits
This course provides a brief overview of DNA and RNA structure and the principles of polymerase chain reaction. It then proceeds to discuss the principles and procedures for real-time PCR, highlighting the advantages over traditional PCR methods and the applications in the clinical setting.
Objectives
- Compare and contrast the structure and functional regulation of DNA and RNA.
- Discuss the basic principles of the polymerase chain reaction (PCR) process.
- Define the detection techniques for the measurement of nucleic acids by real-time PCR.
- Discuss the evolution of traditional PCR to real-time PCR, and the advantages and limitations of both methods.
- State the applications of real-time PCR.
