Question

Which of the following features is shared by all living organisms?

• A. Cell wall
• B. DNA or RNA
• C. Meiosis
• D. Membrane bound organelles

Answer 1

Answer: (B)

DNA or RNA

Cell walls are only present in plant cells, various microorganisms like fungi, bacteria and some protista. Cell walls are absent in all animal cells.

Meiosis does not occur in archaea or bacteria.

All living organisms store genetic information using the same molecules — DNA and RNA.

All individual cells are much smaller and they possess specialized structures which allow them to complete their life functions. In cells, these structures are referred to as organelles. Some organisms have organelles, while others don't.

So, the correct answer is option B.
