I find it interesting that all life on earth use DNA. I've seen
video on how helicase and ribosomes work together to copy DNA
sequences (to RNA) with helicase then recreate them using
ribosomes. Does this process work the same way in the simplest
life forms? Bacteria and other unicellular life that reproduce
through mitosis, for example? I've had a direct look at
Carsonella rudii, which is I believe is the bacterial genome
with the smallest number of genes so far - 184 as well as being
only 160 kb in length. It has a putative DNA helicase encoded in
it. 37 of those genes encode for ribosomal components as well.
If there was ever a bacterium or any living cell (non virus that
is) discovered without a ribosome, you would have heard about
it. nobel prizes all around. So I would say that your answer is
yes. First, mitosis is a eukaryotic process where not only
genome replication and cell division is involved but quite a few
more processes, not the least because there is a nucleus in
eukaryotes. Bacteria simply di
