Directions: Below are the 3 steps in DNA replication. Follow the directions for each step and then answer the questions below. 1. -What is happening to the DNA molecule in the figure? (Explain the first step in DNA replication) -What happens to the DNA molecule during the second step of DNA replication? 3.
New DNA is replicated in strands complementary to old DNA because production of new DNA follows the rules of ___________________________ (base pairing/the double helix). Identifying Structures On the lines corresponding to the numbers on the diagram, write whether the strand
Deoxyribonucleic acid or DNA is the molecule of heredity. It contains the genetic blueprint for life. For organisms to grow and repair damaged cells, each cell must be capable of accurately copying itself. So how does the structure of DNA allow it to copy itself so accurately? Model 1 – The Structure of DNA Nucleotide Phosphate
Students label DNA replication showing how enzymes like helicase, ligase, and polymerase create a new copy of DNA. After labeling, students answer questions about the model.
1. How do the bases in DNA pair up? A - _____ G - _____ T - _____ C - _____ 2. Compare your two “new” DNA molecules (the ones you did on the front) to your actual keychain. How does the order of the bases they compare? 3. What do we call a change in a gene or chromosome? _____ 4. What two cell division processes use DNA replication ...

For each strand of DNA, show the three steps to demonstrate that you could “replicate” the DNA correctly. See the example for details if you don’t recall how. A. Fill in the complementary strand. B. Split the DNA and fill in the complementary strands to …
The enzyme ______________ relieves any tension from the unwinding of the double helix. The enzyme ______________ breaks the hydrogen bonds holding the two complementary parent strands together, resulting in an unzipped helix that terminates at the _______________________.
