Endospore-Forming Bacteria Like Bacillus Species Begin the Sporulation Process with an Asymmetric

question 70

Multiple Choice

Endospore-forming bacteria like Bacillus species begin the sporulation process with an asymmetric cell division to produce two cells with different fates.One will differentiate into the endospore, and the other is the sporangium that will ultimately lyse to release the mature endospore.(Review Process Figure 4.24.) During this asymmetric cell division, one of the compartments does not receive an intact copy of the chromosome.Which compartment can function with only part of the genome and why?

• A)The sporangium; much of the genome is "junk DNA" and not required for endospore maturation.
• B)The sporangium; it supports endospore development and then lyses.
• C)The endospore; the endospore is built from the outside via the sporangium and not from the inside.
• D)The endospore; it is a dormant stage and requires very little to maintain its dormancy.
