Replication vs. Transcription – Complete the table by checking the correct column(s) for each description.
Description
Replication
1. Takes place in nucleus of eukaryotic cell
2. Occurs during S of interphase
3. Occurs during G1 of interphase
4. Nucleotides move in to base pair with both sides of DNA
5. Nucleotides move in to base pair with one side of DNA
6. Involves “unzipping” of DNA
7. Requires enzymes
8. Guanine base pairs with cytosine
9. Adenine base pairs with thymine
10. Adenine base pairs with uracil
11. Produces sister chromatids
12. Occurs in skin cells
13. Occurs in heart muscle cells
