Answer:
Option D
Explanation:
They are unsuitable because eukaryotic proteins before they are synthesized through transcription giving rise to mRNA and translation to proteins undergo various modifications such as splicing (removal of introns and joinimg of the exons) etc due to the presence of introns in the eukaryotic genome which is absent in bacteria.
Thus, bacteria does not have machinery that will perform this functions as it has little to no introns and the products do not have to undergo modifications like eukaryotic genome.
Thus, without this, some functional proteins will not be expressed using the bacteria expression system.
Answer:
D) Both lack membrane-bound organelles and are single-celled.
Explanation:
The answer is D because the main difference between Archaea and Eubacteria is they differ in the formation of their cell wall. Archaea's cell walls are made of uncommon lipids while Eubacteria have cell walls made of peptidoglycan.
A signal reaches a cell mostly in the form of a signalling molecule binding to a receptor on the cell surface. This binding activates a chain of events that amplifies the signal and transfers it inside the cell. Protein kinases phosphorylate proteins and cause their activation or deactivation, or in general modify their activity. When a signalling molecule binds to a receptor, a cascade is activated and the second messengers, such as cAMP, are synthesized. cAMP molecules activate the protein kinases, which phosphorylate specific proteins and activate them.
