Write a 1-page piece on 'DNA duplication and the Polymerase Chain Reaction (PCR).

This week we had a lab walkthrough where I was able to show you around and we focused on a few lab equipment with microbiological Sciences relevance.
Your report for this lab will take the following format:
Write a 1-page piece on the Topic ‘Centrifugation and Bacterial Separation using the Centrifuge’
Write a 1-page piece on ‘DNA duplication and the Polymerase Chain Reaction (PCR)
Write a 1-page piece on ‘Microbial Sterilization and the Autoclave’
You selected 2 media during the lab walkthrough
In a tabular (table format) show the following for each of the media:
What type of media is the media you chose (General Purpose, Selective media, Transport media, enumeration media etc). Which type of media did you choose?
If you are to prepare 350 mL of the media, what grams of the media will you dissolve in 350 ML of distilled water? Start by stating the details at the back of the media as you captured in the lab – how much media is needed to prepare 1 L of media.
