Distinguish between the terms genome and proteome of a single-celled organism.
Explain why modern classification systems based on genome sequencing are far more reliable for determining evolutionary relationships between prokaryotes than traditional methods based on metabolic phenotypes (such as substrate utilization or optimal growth temperatures).
In an evolutionary study of archaea, a researcher measures the diameter of a spherical Methanococcus cell from a transmission electron micrograph.
