Chapter 3, Problem 2Q
Summary Introduction
To determine:
The reason why there are differences between archaea and bacteria.
Introduction:
The domain classification consists of prokaryotes, eukaryotes, and archaea. The prokaryotes include the group of bacteria which are unicellular organisms, without a nucleus and chromosomes condensed in the cytoplasm. Archaea include the group of ancient bacteria. Both archaea and bacteria have evolved from their last common ancestor (LCA).
