 To extract examples, we will review our first session of NCBI using following instructions:
 
-1. Search for RRM1 proteins in NCBI
-2. Select RRM1 protein from *Mus muscuslus*
+1. Search for P53 proteins in NCBI
+2. Select P53 protein from *Mus muscuslus*
 3. Run BLAST on this sequence to identify its homologs
