Question

3. What do nucleic acids and phospholipids have in common?

they both contain phosphate groups

they are both important cell signaling molecules

they are both important energy sources

they are both important for all cell structure

Answer 1

they both contain phosphate groups

Step-by-step explanation:

A nucleic acid has a phosphate molecule at 5’ Carbon. This phosphate bonds with the 1’ Carbon of the next nucleic acid forming a phospho-diester bond. A phospholipid, as the name suggests, also comprises of a phosphate molecule that makes the hydrophilic end of the molecule. Attached to the phosphate molecule is a glycerol molecule and two fatty acid chains (the hydrophobic end of the molecule). Phospholipids are usually amphipathic and are significant components of the cell membrane.
