A scientist introduced mutations in a gene sequence isolated from bacteria. Study the sequence, and identify the steps where the mutations may affect the formation of proteins. In the sequence, black letters stand for protein coding regions and red letters stand for noncoding regions. Protein will not be changed.
Protein may be changed.

lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. so they expose rocks
