On 29th August  Lucienne McCallum from Timstar presented an engaging hands on practical for all Higher Biology students. The sessions involved the students carrying out the process of Polymerase Chain Reaction (PCR). 
PCR is a technique that can be used to create many copies of a piece of DNA in vitro.The amplification of DNA involves the use of primers. The primer is single stranded and is complementary to a  specific target sequence of the DNA strand.  PCR can be used to amplify DNA for forensics, paternity testing and identification of genetic diseases.
The Higher students engaged well with the session and had the opportunity to apply their theoretical knowledge in a practical setting.
