PPT-Replication & Expression of DNA

The structure of DNA encodes the instructions for making proteins and when necessary provides a means of duplicating those instructions 4272017 1 GATTACA intro 4272017 2 Unit 6 Concepts. 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?. 20.1 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.. Learning Objectives. What happens during DNA replication?. How is a new polynucleotide strand formed?. Why is DNA replication known as ‘semi-conservative’?. Putting What We’ve Learnt So Far In To Context.... 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. Replication.
