Thanks
i think 2 is d
5 is a, because prokaryotic cells don’t have a nucleus
For number one I would go with b because viruses are not really alive when they are between hosts and therefore do not “survive” in the usual way. Two is also b because viruses rely on the host for all things and really have no metabolic system of their own. I believe that three is d but you might want to double check on that because both of those might not be strictly necessary although they would help greatly. Four is most likely E but I haven’t studies proteomics in any detail. Five is a because prokaryotic RNA is under almost constant breakdown and is very short lived. I believe that number six is a. You’re going to need to look up number seven on your own although I know that it is not b or e as gene therapy is highly controversial. I don’t know what advances have been made in gene therapy recently and this is a field that changes often so google it I guess or check your text book. I believe that number 8 is e.

5. A difference between prokaryotic and eukaryotic RNA is that:
a. eukaryotic RNA lasts much longer before being degraded
(PROKARYOTES DON’T HAVE A NUCLEUS!)
6. A sequence of DNA that has inverted sequences on either end is found scattered throughout the chromosome of a bacterium.
Um I really don’t know I think it is A maybe???
7. Gene therapy:
d. had apparent success in treating disorders involving bone marrow cells

d. a and c
I think I am right. I didn’t feel like looking up some of these and I figured it would be more beneficial if you did.
