DNA Essay Objectives 1. Understand the semiconservative nature of DNA replication. Realize that the process begins at unique origins of replication, and proceeds bidirectionally. 2. Know that DNA synthesis is catalyzed by a family of enzymes called DNA polymerases. Understand that DNA polymerase has a requirement for a template on which to synthesize the new DNA strand, and for a primer from which to extend the DNA strand. 3. Understand the various functions of the RNA polymerases, such as exonuclease and polymerase activities, and their function in the replication process. 4. Know the other components of the replication apparatus, and their basic functions. Understand the principles of leading strand synthesis and lagging strand synthesis. 5. Realize that eukaryotes require the activity of telomerase to complete the synthesis of their linear chromosomes. The Semiconservative Nature of DNA Replication One property of the genetic material necessary for its function is the ability to replicate (reproduce)...
