DNA and Protein Synthesis Explain the structure of DNA – use the terms nucleotides, antiparallel strands, and complimentary base pairing. DNA contains two long antiparallel strands with four different types of nucleotides (adenine, thymine, guanine, cytosine).The four different nucleotides will join together in complementary base pairings (a->t, g->C) bonded together with 2 or 3 hydrogen […]
