Which of the following statements is not true? a. Archaea and bacteria have different membrane lipids. b. The cell walls of archaea lack peptidoglycan. c. Only bacteria have histones associated with DNA. d. Only some archaea use CO2 to oxidize H2, releasing methane.

Video transcript

Hello everyone and welcome to today's video. So which of the following is true for both bacteria and archaea. Let's go over each of our answer choices so that we may solve this problem. Beginning by answer choice. Archaea and bacteria. You C. 02 to oxidize hydrogen releasing methane organisms that do. These are methanol engines and these are usually going to be organisms that live in very extreme conditions which is characteristic of archaea because of these. We're going to cancel it out because bacteria do not undergo this process. Then we have answer choice. E archaea and bacteria have similar membrane lipids. Well in fact they're going to the membrane lipids are going to be very structurally different because of this. We're going to cancel this out as well. Then we have answer choice. D. Archaea and bacteria have peptidoglycan in their cell wall recall from previous videos that peptidoglycan is a very important characteristic of the bacterial cell wall. Not in the Rko cell wall because of this we're also going to cancel it out. Finally we have answer choice A. Ikea and bacteria like histone proteins associated with their DNA. Well these histone proteins are very important characteristic of U. K. Area but they're not really present in bacteria and Archaea because of this. This is a true statement and we're going to highlight it as a final answer to our question. I really hope this video helped you and I hope to see you on the next one
