All living things are divided into three domains: bacteria, archaea, and eukarya. They have several traits that are specific to each domain or shared across the domains.   Based on this information, what traits would the last universal common ancestor (LUCA) be expected to have? A. Nuclear envelope, introns in genes, and peptidoglycan in cell walls.   B. Histones associated with DNA, circular chromosome, and peptidoglycan in cell walls.   C. Unbranched hydrocarbons in membrane lipids, histones associated with DNA, and introns in genes.   D. Circular chromosome, unbranched hydrocarbons in membrane lipids, and one kind of RNA polymerase.

Prokaryotic evolution

The term evolution means the gradual change or a transformation from a simple or primitive state to a complex or advanced state. Prokaryotic evolution is a concept that involves the evolution of the form and function of most primitive organisms (prokaryotes) through several stages and changes to form diverse life as a part of organic evolution.
