Answer:
Genetic engineers can transfer a specific piece of DNA or genes from one organism to another organism. This is usually done by adapting recombinant DNA methods. In this approach, a gene of interest is cut with restriction enzymes and then inserted and ligated to the host genetic material. This host could be a bacteria or eukaryote.
Example: Biotechnologists can produce insulin by inserting human gene in <em>E. coli</em>. The bacteria replicate its genome fast and produce protein (insulin) which can be extracted and applied to the person who is diabetic. Similar methods have been used for other purposes.
Answer:
The mitochondria is the powerhouse of the cell
When a phage comes in contact with a bacterial host, it attaches itself to the receptors at the outside surface of the cell. Once secured, the phage injects its DNA or RNA inside the cell through endocytosis. Once inside, the host will change according to the DNA or RNA injected.
