Biologist Question:

There is almost no good answer to this question, so don't be specific. If you tell the interviewer that the job you're applying for with his/her company is the perfect job you may loose credibility if you don't sound believable (which you probably won't if you're not telling the truth.) If you give the interviewer some other job the interviewer may get concerned that you'll get dissatisfied with the position if you're hired. Again, don't be specific. A good response could be, “A job where my work ethic and abilities are recognized and I can make a meaningful difference to the organization.”
