Chapter 30.2, Problem 3MI
Summary Introduction
To determine: The condition in which viruses might choose lysogeny rather than lysis and the effect of this on carbon flow.
Introduction: In nature, viruses are categorized on the basis of their life cycles as lysogenic and lytic viruses. Lysogenic virus uses the machinery of the host cell and incorporates its DNA fragment into the cell without degrading the cell. However, the lytic virus kills the host after producing multiple copies of viruses to spread to the next organism. The process of lysogenic conversion means that the viral genome is combined with the genome of bacteria resulting in new properties shown by the bacteria.

Chapter 9 L discusses some oxygen requirement,
grouped. We're going to focus on those that do not necessarily need oxygen for survival. For this part:
aerotolerance, categories under which most prokaryotic organisms can be
1. What oxygen requirement, or aerotolerance, categories allow for an organism to survive in the complete absence of oxygen?
Please list those oxygen requirement/aerotolerance categories where an organism doesn't necessarily need oxygen for growth.
2. Oxygen is toxic to most organisms, even you! One reason we don't see the effects of this is because most organisms are able to
produce enzymes to counteract this toxicity. This is called, "detoxifying reactive oxygen species (ROS)," as discussed in Chapter 9.
In order to survive in the presence of oxygen (if it can), a prokaryotic organism must be able to undergo detoxification of reactive
oxygen species. For each category you listed in 1), please provide:
A. the enzymes that may be lacking/missing in order to detoxify…
Evidence indicating the chloroplasts were originally free-living prokaryotes that subsequently
evolved a symbiotic relationship with a eukaryotic host includes all of the following except:
Ability of chloroplasts to synthesize all their own proteins
Presence of circular DNA in chloroplasts and in free-living prokaryotes
Similarities of rRNA sequences between chloroplasts and free-living prokaryotes
Similarities of structures between chloroplasts and some contemporary free-living prokaryotes

For this particular forum, you'll be able to see other classmates postings even before you post your own. This is so you can present an example that's different from what's already been discussed. Remember that mutualistic interactions are associations that benefit both parties -- so your response should clearly indicate the role each partner plays. Let us know where these organisms are found, what kind of habitat they live in, and any other interesting , pertinent information.
