Final answer:
When choosing a cloning host for making proteins for human use, safety considerations include avoiding production of toxic substances, using hosts with similar protein processing systems, and preventing risks of infection or disease transmission. Transgenic animals like sheep, goats, and chickens have been used to produce recombinant proteins, but careful safety assessments are conducted.
Step-by-step explanation:
When choosing a cloning host to make proteins for human use, several safety considerations must be made. One important consideration is to ensure that the cloning host does not produce any toxic or harmful substances that could be harmful to humans. Another consideration is to choose a host that has a similar protein processing system to humans, so that the proteins produced through cloning are properly folded and functional. Additionally, it is important to choose a host that has a low risk of causing infections or diseases in humans.
For example, transgenic animals such as sheep, goats, and chickens have been used to produce recombinant proteins for human use. These animals are modified to express the desired genes and the proteins are then produced in their milk or eggs. Before using transgenic animals, rigorous safety assessments are performed to ensure that the proteins produced are safe for consumption and do not pose any health risks to humans.
