Genomic and Regulatory Features of Archaea Domain
Eubacteria-like 1.) single-circular
chromosomes with some genes in polycistronic
operons in the same order as
Eubacteria 2.) no 5 cap Eukaryotic-like 1.)
N-linked glycoproteins 2.) shared
resistance/sensitivity to antibiotics 3.) lacks
of fmet 4.) lacks any homology or analogue to
the Shine Delgarno sequence 5.) presence of
tRNAs with introns 6.) most importantly,
transcriptional regulation a) DNA-dependent
RNA polymerase (transcriptase) b) the
consensus archaic promoter is similar in
sequence and relative position to that of
the eukarya promoter c) the polymerase
requires eukarya-like transcription factors for
promoter recognition d) one of these
factors uses a TATA box and is essentially
eukarya TFIID.

  • What questions should be answered?
  • How and When was RNA transferred to DNA?
  • How and When did the genetic code evolve?
  • How and When did translation evolve?
  • How and When did real cell membranes evolve?
  • Where did the nucleus come from?
  • How did Eukaryotic compartmentalization occur?
