True or False and why?

  1. Bacteria living in a volatile (heterogenous) environment would likely have more control element for gene expression than an endosymbiont.
  2. Bacterial gene regulation at the enzyme results in a quicker response compared to regulation of transcription.
  3. Mutations in the bacterial genome are typically lethal in part because bacteria are diploid.

Solutions

Expert Solution

1.Mutations in the bacterial genome are typically lethal in part because bacteria are diploid. (FALSE)

Justification: Bacteria are haploid because it contains onle one copy of chromosome, mutations that inactivates essential genes are usually lethal in nature.

2.Bacteria living in a volatile (heterogenous) environment would likely have more control element for gene expression than an endosymbiont. (TRUE)

Justification: In volatile environment , bacteria faces a lot of stress whereas endosymbiont follow theory of mutualistic relationship. Therefore, bacteria present in volatile environment needs to regulate gene expression thus likely to have more control elememts.

3.Bacterial gene regulation at the enzyme results in a quicker response compared to regulation of transcription. (FALSE)

Justification: This is false statement because transcription and translation are coupled phenomena in case of bacteria, it means gene will be transcribed and translated simultaneouly.
