Which of the following traits do archaeans and bacteria share? 1. composition of the cell wall 2. presence of plasma membrane 3. lack of a nuclear envelope4. identical rrna sequences

2. presence of plasma membrane 3. lack of a nuclear envelope

Explanation:

Both archaeans and bacteria are prokaryotes. The prokaryotic organisms lack the well-defined nucleus and membrane-bound organelles. These organisms have their genetic material present in the cytoplasm itself.

Both archaeans and bacteria have a plasma membrane around their cells. The presence of plasma membrane around cytoplasm is exhibited by all the living beings including all the prokaryotes. Plasma membrane in archaeans and bacteria has the same basic structure. It has two layers of phospholipids in which proteins are embedded.
