Answer: 5 carbon sugar, phosphategroup, nitrogen base What are the base pairing rules (Chargaff's rules)? Answer: A & T and C & G Given the DNA strand-TCACGGTAC.What is the sequence of the complementary DNA strand? Answer: AGTGCCATG What role do the helicase and DNA polymerase play in DNA replication?- Answer: Helicase=unwinds and separates the 2 DNA strands DNA polymerase= moves along each of the template strands, and attaches complementary free-floating nucleotides and also proofreads each new DNA strand. What are the products of DNA replication? Answer: It results in two exact copies of the original DNA molecule.Each new DNA molecule consists of one original ("old") strand and one "new" strand
