    Thanks for the videos! They are a life saver, reading the textbook without someone explaining is hard .

    Koch is pronounced "Coke." It's German for "cook" however the German pronunciation sounds a little bit different from how we English speakers pronounce it.

    At 8:08 (the slide about Lytic cycle), you said the injected DNA mingles with "our DNA". I thought the Lytic Cycle only applied to Prokaryotes? In the picture itself there is a circular DNA with no organelles, making it a bacteria.

      The cell shown was a prokaryote, but eukaryotes can be infected as well. All the existing dna gets cut up anyway so number of chromosomes or circular vs linear isn't really a big deal.

    Hi, what edition are you using? My class uses 7th and I have 8th, we have a test on 18 and 19 from 7th. Which videos should I be looking at?

    • @ScienceWithJohnston
      @ScienceWithJohnston  6 років тому +2

      I did these with the 8th ed order of chapters, but not much changes between versions. The chapters are generally similar content, they just reorder the chapters or merge/split a chapter to make it seem different. So just verify the titles of the 7th ed and make sure they match.
