1. As a supervisor in the infection-control unit, you hire a local microbiologist to analyze samples from your hospital's hot-water tank for microbial contamination Although
she was unable to culture any microbes,
she reports that basic microscopic analysis
revealed the presence of cells 0.8 um in diameter that lacked a nucleus.
Transmission electron microscopy showed that the cells lacked membrane-bound
organelles but did contain ribosomes. Which domain of life do you hypothesize
these cells represent? Discuss any additional analysis that could be performed to
determine this classification most accurately.
