Answer: The prokaryotic cells lack any membrane-bound organelles, including a nucleus. Instead of that, prokaryotic cells simplify have an outer plasma membrane, DNA nucleoid structure, and ribosomes.
Amino acids link together to form a protein. A nucleic acid is held together by the sugar-phosphate complex. A protein is held together by the carbon-carbon bonds. The diagram shows the basic structure of a biomolecule.
<h3>DNA and RNA bases are also held together by chemical bonds and have specific base pairing rules. In DNA/RNA base pairing, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G).</h3>
