    Thank you so much for making these videos. They have been such a huge help for my AP Bio class! I could listen to my teacher's lectures all day and not understand anything but you understand how to explain concepts in a way that students understand. Thank you!

      100% my teacher is garbage and just reads off of the college board PowerPoints that you can find online. I want to slam my head into the wall every class.

    Thank you so much for this! I have a 6 chapter (16-21) test/FRQ this week and I did not understand anything. Your videos have helped soooo much I’m actually comprehending the material.

      This guy is great. My teacher just reads us a PowerPoint everyday using her monotonous voice. It’s terrible

    at 3:18 you said the fewer products it can produce from the gene is better? why is it this way? isn't more products from fewer gene better?

      @siri4597 3 года назад +1

      Ik it’s a year late lol but i might as we’ll say it for anyone else. Basically, if it produces less, it can produce the specific genes needed. If it produces too many genes, it’s possible that it will produce genes that are unnecessary and will just waste energy to make...hope that made sense idk

    is turning a gene "off or on" technically mean whether a protein which is coded by those genes is synthesized or not?

    • @ScienceWithJohnston
      @ScienceWithJohnston  Год назад +1

      Yes in a general sense, although not all genes code for proteins so there are some cases where the RNA is the functional end product.

    Is this from Campbell biology 9th edition?

    • @ScienceWithJohnston
      @ScienceWithJohnston  6 лет назад +2

      I originally did these based on the 8th ed, but I know the 9th and 10th are very similar (I have used materials from each). I haven't looked at the 11th ed yet to say but I suspect its about the same as well.

    I really like your videos but the intro gives me anxiety. I am 21 years old and afraid of your intro.

    @brilynbrecka4301 7 лет назад

    These videos are great. However, which book is this following? In my book, chapter 18 is entitled “the genetics of viruses and bacteria”. The videos have followed along with everything else so far. And the study guide on the Campbell website is also off.

      After 2016, Pearson has changed it's style. However, Mr. J makes his own ways to learn the subject.
