One hypothesis that has been proposed to explain the development of viruses suggests that viruses were beneficial because they allowed for rapid gene transfer, especially in prokaryotic cells, and therefore increased genetic diversity. If most bacteriophages were temperate, then this could have increased horizontal gene transfer between prokaryotic cells and potentially could have increased fitness. With respect to this hypothesis, why would it matter whether the bacteriophages were temperate or virulent?

a. Temperate phages are capable of lysogeny and their genetic material can be integrated into the host genome, causing damage rather than increasing fitness.

b. Virulent phages are capable of lysogeny and their genetic material can be integrated into the host genome, causing damage rather than increasing fitness

c. Temperate bacteriophages are capable of both horizontal and vertical gene transfer, allowing a wide range of ways to increase genetic diversity. Virulent bacteriophages are not capable of either.

d. Temperate phages don't immediately kill their hosts.

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression. c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression. d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
