#BioDub DNA Map from the Chapter 12-1 Notes

• The deoxyribose-phosphate sequence make up the DNA backbone
• The A's, T's, G's, & C's are the nitrogenous bases
• G's & C's form 3 weak hydrogen bonds between them
• A's & T's form 2 weak hydrogen bonds between them
• A's & G's are purines
• T's & C's are pyrimidines
• 1 nucleotide consists of a phosphate, a deoxyribose, & a nitrogenous base
