As a scientist working for an anti-bioterrorism task force, you are asked to evaluate some biological samples for the presence of Yersinia pestis, the organism that causes the plague. After confirming that the samples do contain Y. pestis, you instruct your team to begin sequencing the strain. Since the genome sequence of Y. pestis is already known, why would sequencing this strain be useful?
A. To provide better data for the genome database B. To establish the course of infection, and determine whether the strain is altered by causing infection C. To help determine the source of the strain, and learn whether it has been genetically engineered D.
