DNA Structure Blueprint of DNA is in order of base pairs Order of bases copied in making new DNA o Prior to cell division chromosomes are copied Order of bases used as template for making proteins The next topics are based on copying the order of base pairs in DNA: 1. DNA replication 2. Protein Synthesis (also involves RNA) Base Pairs in DNA Sequence of base pairs in DNA must be copied Passed on to daughter cells in cell division (meiosis/mitosis) Accomplished during DNA replication Weak bonds between base pairs break and two strands of DNA split – like the halves of a zipper Exposed nitrogenous bases attract new nucleotide mates (T to A, C to G) Both strands act as blueprints for assembling new DNA DNA replication prior to cell division Enzyme moves along DNA molecule Splitting DNA into two strands Assembling matching bases with exposed bases Resulting in two identical strands of DNA The Role of RNA in Cell Replication (Chapter 12)
