Why is A, T, C, G and U called the universal code? Why are proteins important to living things? Explain!

Answer 1

A (Adenine), T (Thymine), C (Cytosine), G (Guanine), and U (Uracil), are the amino acids that make up DNA and RNA. They also make up proteins. These five amino acids are found in every living thing, which makes them "universal". Proteins are important because they are responsible for so. many. functions. Literally! Proteins help catalyze reactions, transport things like oxygen throughout our body, carry messages between cells, aid in our immune system, and even aid in the formation of new molecules.

Hope this helps!
