<span>one of the special feature of bacterial cells that helps it survive in hostile environment is its : ability to form endospores
Endospores are resistant to chemical, stress, and some form of radiations, which make bacteria abble to survive in the environement</span>
Answer:
Human insulin
Explanation:
The process where by region of a DNA that codes for a particular function is transferred between organisms into cells Is described as gene transfer. This process can be used to enhance the mechanism of producing a gene that is not originally present in such organisms before. Therefore if the gene that code for insulin is inserted into a bacterial vector , the offspring of such bacteria will be able to synthesize insulin in their cell
The correct answer is D: I and II only.
Viruses have protein capsids, which protect their genetic material. This capsid sometimes is covered by viral envelopes which have glycoproteins on their surface. Glycoproteins help in the process of binding to the host cell and infecting it. In this example, virus III has the structure of a bacteriophage and it does not seem to have glycoproteins. Bacteriophages use their tail fibers to attach to the bacterial host and inject their genetic material. On the contrary, viruses I and II have glycoproteins sticking out of their envelopes.
Answer:
Cell, nucleus, chromosome, gene
