CP Biology – DNA Structure, Replication, Translation and Transcription Guide --with Objectives and Study Guide Every cell contains DNA, which directs protein synthesis. Instructions for creating proteins are encoded in the nucleotide sequence in DNA. The DNA sequence codes for the specific sequences of amino acids that comprise protein characteristics. OBJECTIVE #1 Describe the basic structure (double helix, sugar/phosphate backbone, linked by complementary nucleotide pairs) of DNA and describe its function in genetic inheritance.
