Which of the following statements is incorrect regarding the genetic diversity found in living organisms on our planet?
1) Prokaryotic genomes are typically much smaller than eukaryotic genomes.
2) All life on our planet uses nucleic acids to store information, proteins to carry out these instructions, and uses the same code to convert the information in nucleic acids into proteins.
3) Only eukaryotes have linear chromosomes; these are circular in archaea and bacteria.
4) Prokaryotic organisms often have extra pieces of DNA in addition to their chromosomes, but these are rare in eukaryotic organisms.
5) Archaens share more genetic traits with eukaryotic organisms than with bacterial organisms, which is why archaen and eukaryotic domains are thought to share a more recent common ancestor together than they do with bacteria.
