PPT-DNA Replication

201 part 2 DNA replication Earlier on in this unit we learned about mitosis or cell division In order for mitosis to occur and chromosomes to duplicate themselves the DNA must copy itself exactly. GO TO . BIOINTERACTIVE WEBSITE. DNA replication questions. Why is DNA replication so important?. In what part of the cell cycle does DNA replication occur?. What enzyme brings in the new DNA nucleotides that form complimentary pairs with the old DNA strand?. Chapter . 7.2. Processing of Genetic Material. What is DNA Replication. The process by which the DNA within a cell makes exact copies of itself. Balance of speed and accuracy. Used for growth, repair and embryonic development. Objectives:. 1. Summarize the roles of the different enzymes involved in replication of DNA.. 2. Explain how the leading and lagging strands are replicated differently . Semiconservative.
