 * [|Nucleic Acids]
 * **An organic compound whose molecules carry genetic information and is made up of one or two chains of monomer units called nucleotides**
 * **[|DNA]**
 * **deoxyribonucleic acid**
 * **largest molecules in cells**
 * **carries all genetic information**
 * **double helix**
 * **nitrogenous bases**
 * **Nitrogenous Base Pairs**
 * **A-T**
 * **G-C**
 * **[|DNA Replication]**
 * **Process by which an identical copy of the original DNA molecule is formed. The process begins when DNA un-zippers with the help of the helicase enzyme.** The two strands are now separated and nucleotides make two new DNA molecules.
 * [|RNA]
 * ribonucleic acid
 * synthesis of proteins
 * differs from DNA in the following ways:
 * ribose instead of deoxyribose
 * uracil instead of thymine (A-U is found in RNA whereas A-T is found in DNA)
 * single stranded
 * much smaller
 * RNA Synthesis
 * ribosomes are organelles that are composed of RNA and proteins
 * ribosomes are site of protein production
