Gene Expression Through CRISPR: Unlocking the Butterfly Effect

This project uses CRISPR-Cas9 gene editing to investigate the roles of specific genes in butterfly development. Students will target genes associated with wing pattern formation to observe phenotypic changes.

Gene Expression Through CRISPR: Unlocking the Butterfly Effect

Hypothesis

If CRISPR-Cas9 can successfully edit genes associated with wing patterns in butterflies, then observable changes in wing coloration and patterns will occur.

Step-by-Step Procedure

  1. 1

    Prepare CRISPR-Cas9 guide RNA for the target gene.

  2. 2

    Inject CRISPR complex into butterfly larvae using a sterile needle.

  3. 3

    Place larvae in an incubator and maintain optimal conditions.

  4. 4

    Monitor development and document any changes in wing patterns.

  5. 5

    Use a microscope to observe detailed wing structures.

  6. 6

    Compare edited butterflies to a control group.

  7. 7

    Record phenotypic differences and analyze data.

  8. 8

    Repeat the experiment for consistency.

  9. 9

    Document any unexpected results or mutations.

  10. 10

    Review ethical implications of gene editing in insects.

Expected Results

Edited butterflies are expected to exhibit altered wing patterns, demonstrating the role of specific genes in morphological traits.

Variables

Independent Variable

Target gene for editing

Dependent Variable
