What This Document Is
This document is a lab activity and accompanying answer key for BIO 102, Introduction to Biology at Emory University. The lab, titled “Bio 10 Evolution Lab: Amino Acid Analysis,” explores how protein sequences can be used to understand evolutionary relationships between different organisms. It focuses on analyzing amino acid differences in hemoglobin and cytochrome c.
Why This Document Matters
This lab is designed for undergraduate biology students learning about molecular evidence for evolution. It’s used to reinforce concepts covered in lectures and textbooks, providing hands-on experience with data analysis and interpretation. Students will utilize this lab to develop skills in comparing biological data and drawing conclusions about evolutionary history. It’s particularly relevant after or alongside coursework on DNA, protein synthesis, and evolutionary theory.
Common Limitations or Challenges
This document provides the *answers* to the lab questions, but it does not teach the underlying biological principles. Students should already have a foundational understanding of proteins, DNA, and evolutionary concepts to effectively use this resource. It also assumes access to the original lab manual with the amino acid sequence data (Figure 1). This preview does not provide the full sequence data itself.
What This Document Provides
The full document includes: a pre-lab question section with predicted answers, detailed instructions for comparing amino acid sequences in hemoglobin and cytochrome c, and completed answers for the analysis activities. It also contains vocabulary definitions related to the lab (e.g., compare, sequence, related, identical) and teaching tips for instructors. This preview only provides a summary of the document’s content and purpose; the actual data tables and completed analyses are within the full document.
