Recently, we were discussing standard PCR and also qPCR (quantitative, real time, PCR).
You can download the specific slides/images in the two methods handouts linked above.

You can download the specific slides/images in the two methods handouts linked above.
1. The PCR topic: Please watch my three mini-lecture videos below covering various aspects as indicated below.
2. Complete the Quiz below in the yellow box below the PCR videos (feedback provided to assist your learning).
3. Ensure you have performed the PCR pre-practical quiz (see 13th March e mail from me). Important to do this.
4. Regarding your last lab, complete this virtual lab on PCR and also this one on gel electrophoresis by Friday 3rd April. Note that with the agarose gel, we stain with SYBR safe during the process, while in this example they stain the DNA at the end with a different chemical. As a 'virtual lab manual exercise', please submit one 250 word (max) summary of these virtual sessions to Moodle by April 3rd.
5. Reminder: CA exam takes place at 1pm online on Friday 27th March (see recent e mail sent last Friday).
