7Q1-Describe the double helix nature of DNA. Why is it that DNA is always found as a double stranded, antiparallel and complementary molecule? Correct Answer-The two strands of DNA run in anti-parallel directions and attached to each sugar is one of four types of nitrogenous bases, which make hydrogen bonds. It is antiparallel and complementary so that it has two copies as a safety measure. 7Q2-What are histones and the structural components(DNA/proteins)of a nucleosome? Correct Answer-Histon...
