Binds to the DNA strand at a specific sequence of the gene called a promoter; Unwinds and unlinks the two strands of DNA; Uses one of the DNA strands as a guide or template; Matches new nucleotides with their complements on the DNA strand (G with C, A with U -- remember that RNA has uracil (U) instead of thymine (T))

Examples of organic molecules include sucrose, cellulose, triglycerides, phospholipds, proteins and deoxyribonucleic acid. Organic molecules are defined as molecules that contain carbon and hydrogen. They are typically divided into four main classes: carbohydrates, lipids, proteins and nucleic acids. Continue Reading.
