She is puzzled that the clone does not have an effect, even though she knows, based on available mutants, that loss of the function of this gene causes worms to die as larvae. You look at the sequence of the DNA she used to make the feeding clone and discover that it corresponds to an intron in the gene. What would you say to the student to explain why her experiment did not succeed

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.

Organ systems are composed of organs, organs are composed of tissues, and tissues are composed of cells. this pattern is organized into levels. organization based on levels can be found in what
