Ward's® AP Biology Investigation 9: Genetics and Information Transfer: Restriction Enzymes

Meets AP Science Practices 3 and 6

In this investigation, students will use electrophoresis technology to analyze DNA sequence by fragment analysis. Simulating the results of a Southern Blot DNA Fingerprint, students will compare fragments of known size to fragments of an unknown size to calculate relative molecular weights and match fragment patterns. Further self-guided experimentation is explored as they investigate parameters of various factors that relate to DNA technology and restriction enzyme analysis.

The Only Kits Aligned with AP Science Practices. Ward's AP Biology Investigations provide complete coverage of the Four Big Ideas and Seven Science Practices to help you meet new AP Biology curriculum standards and prepare students for real-world success in college and research-level labs. Each investigation follows a series of three parts, beginning with a structured lab investigation, followed by a related guided inquiry investigation with thoughtful assessment questions, and finally, suggestions to encourage students to formulate their own questions and explore further self-guided experimentation. This complete series of investigations emphasizes the progression to fully student-directed investigations and builds competence in all of the science practices, helping students:
• Practice concept application instead of fact memorization.
• Focus on self-guided experimentation instead of step-by-step lab procedure.
• Investigate real-world concepts with greater curriculum flexibility.
• Apply problem-solving skills to strengthen student inquiry.
