<h2>Answer:</h2><h2 /><h2>DNA molecules are a precursor to self-replicating RNA molecules, which are used to build proteins. Early RNA molecules were able to self-replicate, which helps to explain why all organisms share the same genetic code.</h2>
Answer:
Explanation:
The components of the cell membrane consists of lipids that includes the cholesterol and phospholipids other components includes the carbohydrates, and proteins. The phospholipid forms the basic structure of the cell membrane. The cholesterol molecules are scattered in the lipid bilayer, these help the membrane in the fluid consistent state.
The main function of the plasma or cell membrane is the protection of the cell from it's surrounding.
