A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. Although the gene was s
kirza4 [7]

Answer:

Option (3).

Explanation:

The process of the transcription and translation is quite different in case of prokaryotes and eukaryotes. Transcription and translation is couple together in prokaryotes whereas it takes place in separate compartment in case of eukaryotes.

The gene has been transferred from the eukaryotes to prokaryote but the protein produced is quite different. This might occur due to the presence of introns in the eukaryotes whereas prokaryotes do not have introns. In case of eukaryotes, the protein express after the splicing process but no splicing occurs in prokaryotes and give different product.  

Thus, the correct answer is option (3).

Hunter-Best [27]

Which elements are most often the limiting nutrients for plant growth nitrogen, potassium, phosphorus

 In the majority of ecosystems, nitrogen (N) and phosphorus (P) are the two nutrients thought to be restricting autotroph (plant) growth.

  • N and P are becoming more readily available in the biosphere due to rising fertilizer use, as well as the production of reactive N during various combustion processes.
  • with N and P. In both studies, the authors concluded that ecosystems are frequently both N and P limited
  • The limitation brought on by one nutrient is independent of the other in the case of independent nutrient co-limiting.
  • The availability of one nutrient influences the intake of another nutrient in biochemically dependent co-limitation; the last two kinds of co-limitation do not directly correlate in the system.
