Yep, we are living in challenging and extraordinary times. The COVID19 changes and dictates rules, but training of future health professionals is going on.
Within a fantastic RCSI summer training programme for medical students, our team ran essential practicals on the isolation of genetic material and the use of polymerase chain reaction, known as PCR, to detect differences in normal and modified genomic DNA.
Polymerase Chain Reaction, or simply PCR, was conceived and validated by biochemist Kary Mullis in 1983. This discovery revolutionised many scientific fields that dealt with genetic material and was awarded a Nobel Prize in Chemistry in 1993. PCR allows rapid generation of small identical fragments of DNA. The fragments can be visualised, their size and number can be calculated. It has become a standard procedure in molecular biology and pathobiology screening. The COVID19 PCR test is actually an advanced modification of Mullis’ invention.
All students successfully set up individual PCRs to our great satisfaction, and the results are presented at the right bottom corner.
