Chapter 10, Problem 2R
Here is some additional information on the organisms in question 1:
| Organism | % DNA Hybridization |
| A and B | 5–15 |
| A and C | 5–15 |
| A and D | 70–90 |
| B and c | 10–20 |
| B and D | 2–5 |
Which of these organisms are most closely related? Compare this answer with your response to review question 1.

Students have asked these similar questions
Choose the one answer that fits best. Which of the following statements regarding bacteria is NOT correct?
a.
During conjugation, two bacteria exchange genetic information directly via pili
b.
Bacterial populations have a higher mutation rate because their DNA Polymerases do not have proofreading capability
c.
Bacterial growth by binary fission is exponential and each division usually takes only a couple of hour or less
d.
Plasmids carry just a few genes and are replicated independently from the bacterial chromosome
e.
Cocci that are arranged in clusters/bunches are called staphylococci
In the table, you have to identify the character for Genus Identification of the Cyanobacterium E (see image). Thank you.
You did not answer what was asked in the table above, you only defined or gave the meaning of the morpho-cytological characteristics which was not asked.
