Thank you so much! I have viewed at least 20 videos attempting to explain the Ames test. You are the only one that explains the test clearly, so that it makes sense. My professor is a nightmare. WHY do we even need them?
Wow, thank you for explaining this so well! I have googled, watched videos, re-reading the same paragraph in my book and I could not figure it out. I finally understand it! Thank you!
Bruce Ames produced many mutants using UV light. He used this specific mutant because it was easy to test the possible mutagens by using media not containing histidine
@@Dr.Raymond Thanks for the video! but this test is suitable for all kinds of possible mutagens, right? so how do all of the possible mutagens do cause the same mutation - histidine synthesis - and not many other possible mutations that we can not observe in this test. In otherwords: Do all mutagens induce this specific mutation?
@@303-e5r It is actually more difficult to reverse a mutation than to cause a mutation. The Ames test determines if the chemical can reverse the mutation the bacteria already have.

Thank You Queen. You explain it very clearly :)
excellent explanation, thank you!
Thank you!
Does somebody know why the Mutagene only affect this one gene? Shouldn‘t other genes be affected by the mutagene aswell?
