Okay, I'm going to ask a question, and then try to answer it, and see if I'm right.

QUESTION: If N.Eq. lacks nearly all genes for lipids, cofactors, amino acids, and nucleotide biosynthesis, shouldn't it be classified as a virus?

Possible Answer: It's because of the "lacks nearly" phrase, isn't it. It does carry some genes for its own lipids, etc., while viruses don't carry any of these genes. (?)

Another question: Since I know very little of the genome of viruses, what exactly does the viral genome encode for?

Note: As always, thanks for the blog, and thanks for the TQ's! I find them actually fun to ponder. The blog is a great way to learn and pick up little bits of advanced biology concepts. I'm going to be like a walking textbook by the time I go off to a 4-year university (LOL)!

See a discussion of what's of a virus in TQ#6, which includes a comment of yours. A popular view of the distinction is that a virus breaks up into its constituents during replication, something a cell never does. You'll see more about this in the blog soon. The genes are carried by viral genomes is a big question, as they vary between a few and many hundreds. Mimivirus is said to have some 900!
