"Modification of histones has been studied for some time, now we are
moving to understand the modification of something that modifies
histones," Shen says of INO80.
Shen's research is conducted in yeast, but the pathways involved are
conserved in all forms of life with complex cellular organization,
known as eukaryotes, right on up to humans, Shen notes."
It seems to me that repair mechanisms are essential for life. Are
there any examples of organisms that lack these complex systems?
Repair systems are found in all bacteria and eukaryotes that we have
looked for them in, but they are missing from viruses. Some viruses
do not even use host repair genomic repair systems, although they
might depend on them indirectly for up keep of host translation
systems.
If you are claiming that repair systems might be required for
lifeforms, the claim is untenable at this time. You are just looking
at the extant organisms that have been in competition for living space
and resources for billions of years. We only see the survivors.
