Biochemistry+Nucleic+Acids

__**1. Deoxyribonucleic acid**__ **(DNA)**
 * __NUCLEIC ACIDS__**
 * Largest molecules in the body
 * Contain **C, O, H, N, and P**
 * Polymers
 * Monomer = nucleotide
 * Composed of nitrogen base, a pentose sugar, and a phosphate group


 * __DNA structure__**
 * __2. Ribonucleic Acid__ (RNA__)__**
 * Four bases:
 * Adenine (A), Guanine (G), Cytosine (C), and Uracil (U)
 * Pentose sugar is ribose
 * Single-stranded molecule mostly active outside the nucleus
 * Three varieties of RNA carry out the DNA orders for protein synthesis
 * Messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA)


 * ENERGY – The Biological coin:** Adenosine triphosphate (ATP)
