Undergraduate Lecture | DNA structure, replication and applications of the Polymerase Chain Reaction (PCR), by Michael Pyne

Tuesday, June 14, 2022 11:30 am - 12:30 pm EDT (GMT -04:00)

The Chemical Engineering Department is hosting a special undergraduate lecture on DNA structure, replication and applications of the Polymerase Chain Reaction (PCR).

Abstract: 

In response to the global COVID-19 pandemic, the acronym PCR has become commonplace in everyday vernacular. However, many people are unable to define PCR or describe the mechanism involved. This lecture will provide a broad overview of the polymerase chain reaction (PCR) and its application in forensics, diagnostics, and biotechnology. I will begin by introducing nucleic acid structure and chemistry, including nitrogenous bases, nucleotides, and both DNA and RNA structures. By emphasizing the complementary structure of DNA, I will outline how DNA is replicated in vivo. Finally, I will introduce PCR as an in vitro engineering tool and we will discuss its broad applications, including its recent role in COVID-19 diagnostics.

By the end of this lecture, students will be able to:

  1. Distinguish DNA and RNA structures
  2. Draw and recognize nitrogenous bases, nucleosides, and nucleotides
  3. Outline the key steps and enzymes involved in DNA replication
  4. Describe the theory and mechanism of PCR; and
  5. Outline common applications of PCR in medical diagnostics, forensics, and biotechnology
