Ib Biology 2 7 7 1 Slides Dna Replication Dna replication 7.2.1 state that dna replication occurs in a 5? → 3? direction. dna replication occurs in a 5'→3' direction. 7.2.2 explain the process of dna replication in prokaryotes, including the role of enzymes (helicase, dna polymerase, rna primase and dna ligase), okazaki fragments and deoxynucleoside triphosphates. 7. a = t and c = g, they are complementary the way the molecules fit together makes it very unlikely that they will bond with the wrong partner. so the genetic code is faithfully copied during replication when things do go wrong, we have a mutation! 2.7.1 the replication of dna is semi conservative and depends on complimentary base pairing.
Ib Dna Structure Replication Review Key 2 6 2 7 7 1 Explanation of the steps to dna replication (in prokaryotes) and discussion of enzymes used and differences between leading and lagging strands. ib 2016 exam. Cie. spanish language & literature. past papers. other subjects. revision notes on 7.1.2 mechanism of dna replication for the dp ib biology: hl syllabus, written by the biology experts at save my exams. Topic 7.1 dna structure and replication. in the dna structure and replication we will extend our knowledge on the dna structure from topic 2.6. this unit will also focus on the individuals responsible for the discovery of the dna helix and proving that dna is the genetic code. this unit will last 3 school days. Dna replication. the process of making an identical copy of a dna molecule, using existing dna as a template for the synthesis of new dna strands. helicase. this enzyme unwinds the dna helix at the replication fork, breaking the hydrogen bonds, to allow the resulting single strands to be copied. histone.
