Macromolecules Continued, Proteins and Nucleic Acids

It is only in the nature of the varian (R) that amino acids differ from another.  There are only about twenty differetn amino acids that occur in the protein of living organisms, although there are about 2000 natural and artifically made amono acids.

There are ten amino acids that cannot be synthesized by the body and must be obtained in the diet.


Nucleic Acids:
If proteins are the building blocks of life, then nucleic acids are the blue print.The DNA has the instructions and directs the RNA in the functioning of the cells and the synthesis of proteins.
