I. The short arm of human chromosome 17 contains the growth hormone-hCS cluster.

II. Growth hormone increases circulating IGF-I, which in turn exerts a direct inhibitory action on growth hormone secretion from the pituitary.

III. Growth hormone secretion is decreased in persons deprived of rapid eye movement (REM) sleep.

IV. Growth hormone secretion is induced by thyroid hormones & inhibited, by cortisol.

In one taxonomic classification, Archaea, Eukarya, and Bacteria represent the three major domains of life. Eukarya utilize the general transcription factors TBP (TATA-binding protein) and TFIIB in transcription, whereas Bacteria do not. At least one member of Archaea has a protein similar to TBP and a protein similar to TFIIB. Based on this observation, which of the following scenarios is most likely?
