Table 1: Record the results of your analysis of bacterial cells including G+C content.
Sample   Shape   Arrangement   Gram + or Gram -   GC Content   Species
1
2
3
4
5
6
7
8

Questions:
1.   Which of the species you identified will have DNA with the lowest melting temperature?

2.   You test a new unknown bacterial sample and find it gram + and has a G+C content of 55%. What can you conclude?

3.   You test another new unknown bacterial sample, and find the G+C content is identical to one of the samples you have already identified, but the rRNA gene sequence contains one base that is different. What can you conclude?

4.   According to your data, which two species that you identified diverged the longest time ago?

5.   List one of your identified bacteria that has a thick cell wall.
