Dna Structure And Function Worksheet Ap Biology Answer May 2026

If one strand of DNA has the sequence 5’-ATTCGAGC-3’, what is the complementary strand? Be sure to label the 5’ and 3’ ends.

Hydrogen bonds are relatively weak, allowing the two strands to be easily “unzipped” by enzymes like helicase without breaking the covalent bonds (phosphodiester bonds) within each strand. This allows each strand to serve as a template. Dna Structure And Function Worksheet Ap Biology Answer

| Feature | Leading Strand | Lagging Strand | |---------|----------------|----------------| | Direction of synthesis | Continuous 5’→3’ | Discontinuous 5’→3’ (Okazaki fragments) | | Requires multiple primers | No (one primer needed) | Yes (many primers needed) | | Template strand orientation | 3’→5’ (toward replication fork) | 5’→3’ (away from replication fork) | If one strand of DNA has the sequence
