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.. 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. 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.... The function of DNA in the cells is to. preserve genetic information.. transfer genetic information to new cells as the strands of DNA are copied.. DNA Replication. In .
