We know that the OPN1LW gene is associated with colorblindness. While this gene is present in all humans, colorblindness affects only a few. What is different about the gene in those affected by colorblindness? Perhaps the answer lies in the level of expression of the OPN1LW gene. A gene's expression is regulated by various elements in the human body. Let's see if we can bioinformatically identify the regulatory elements of our gene of interest.
Molecular Biology concepts
- Scan the genome upstream of the sequence looking for sequences that match criteria for regulatory sequence.
Find motifs in our sequence and compare them to motif databases.
