Review the Chapter Concepts list. These are concerned with the replication and synthesis of DNA. Write a short essay that distinguishes between the terms replication and synthesis, as applied to DNA. Which of the two is most closely allied with the field of biochemistry?
▪Genetic continuity between parental and progeny cells is maintained by semiconservative replication of DNA, as predicted by the Watson-Crick model.
▪Semiconservative replication uses each strand of the parent double helix as a template, and each newly replicated double helix includes one "old" and one "new" strand of DNA.
▪DNA synthesis is a complex but orderly process, occurring under the direction of a myriad of enzymes and other proteins.
▪DNA synthesis involves the polymerization of nucleotides into polynucleotide chains.
▪DNA synthesis is similar in prokaryotes and eukaryotes, but more complex in eukaryotes.
▪In eukaryotes, DNA synthesis at the ends of chromosomes (telomeres) poses a special problem, overcome by a unique RNA-containing enzyme, telomerase.
▪Genetic recombination, an important process leading to the exchange of segments between DNA molecules, occurs under the direction of a group of enzymes.
