Answer:
Introns are the non coding regions that are available in the eukaryotic genes, before being transcribed they get spliced out. Prokaryotic genes do not have introns and so the cells do not have intron splicing enzymes and hence cannot remove introns from the RNA. Hence if introns are present in the mouse gene, they will not be removed after it is transcribed in E.coli. If such RNA with introns is translated, it results in an altered protein with extra aminoacids or an incomplete protein.
1. The prokaryotic RNA polymerase does not recognize the eukaryotic promoter, so there is no transcription. A eukaryotic gene that will be introduced into bacteria for expression must be engineered to have a prokaryotic promoter.
2. There is no Shine–Dalgarno sequence in the eukaryotic gene promoter, so even if an mRNA is produced, the prokaryotic ribosome will not efficiently recognize the translational start site. If a prokaryotic promoter is used to express this gene, it should have the Shine–Dalgarno sequence within it.
The troposphere is the atmospheric layer closest to the planet and contains the largest percentage (around 80%) of the mass of the total atmosphere.

Answer:
The Gonads.(granulosa and sertoli cells)
Explanation:
These are the sources of inhibin in the Gonads. Specifically, the granulosa cells of the female ovaries produced these hormones,while the sertoli cells in testes of males performed the same secretions.
These hormone exits in two forms as Inhibin A and B. Generally, FSH control the granulosa cells and sertoli cells functions and activities.Thus the role of these hormone is to use negative feedback mechanism to control the influence of the FSH on the gonads.
Generally the Oocyte that is lodged in the primordial ovarian follicle is covered by a single layer of cells which are formed from the ovarian surface epithelium,These cells layers are called the Granulosa cells.
The major function is the secretion of oestrogen,under the influence of FSH.It is this activity that is controlled by the Inhibin hormone.
