Answer:
А. The recombinant bacterium will produce human insulin using its own transcription and translation machinery
Explanation:
This question is describing genetic engineering, which aims at producing desirable traits in organisms. In this case, the gene that encodes insulin protein in humans is inserted into the plasmid (extra-chromosomal DNA) of a bacterium. The plasmid is then inserted back into the bacterium to become a RECOMBINANT BACTERIUM.
The recombinant bacterium containing the insulin gene will produce human insulin (protein) using its own transcription and translation machinery. This genetic engineering procedure is used to mass produce insulin protein, which is administered as medicine to humans who cannot produce the protein.
Answer:
Explanation:
Because of their underground lifestyle, caecilians have little need to see or hear. So, their eyes are tiny in some species or hidden under the skin or skull in other species, making just gray bumps for eyes.
