Answer:
C. RNA polymerases.
Explanation:
Bacteria has a primitive type of RNA polymerase while archaeal RNA ploymerase is more advanced and complex than that of bacterial. The structure of archaeal RNA ploymerase has more resemblance with RNA polymerase II of eukaryotes. The RNA polymerase of bacteria requires sigma factor for transcription initiation whereas the RNA ploymerase of archaea requires transcription factors for transcription initiation just like eukaryotes.
The eocene organisms had clear primate characteristics like a postorbital bar, opposable thumbs, nails, and a large brain are Omomydids and Adapids.
The adapids were lemur like primates and the omomydids which includes the probable ancestors of apes and monkeys and Tarsiidae (tarsiers). They are organisms of the eocene epoch present about 34 to 55 million years ago.
They are considered to be the early primates. Their primates characteristics are forward oriented eyes, postorbital bar, opposable thumbs, nails, large brain and adaptation to live in the tree.
