1. Use Entrez to find the human myoglobin DNA sequence. Check the brief description of myoglobin protein.
2. Use Entrez to find the myoglobin protein sequences of the following 20 mammals.

3. Find a multiple sequence alignment program on the internet, and align the 20 protein sequences you found.
4. Go to blast server at http://www.ncbi.nlm.nih.gov/BLAST/, click protein-protein blast
5. Copy myoglobin protein sequence to BLAST server and do a homology search.
6. Check some high-scoring results and low-scoring results. What are they?
