Final answer:
To produce the protein found in a chicken's liver, scientists can use recombinant DNA technology to clone the gene responsible for the protein into a vector. This vector can then be introduced into suitable host organisms, such as bacteria or animals, which will produce the protein using their own cellular machinery.
Step-by-step explanation:
In order to make a protein once the gene responsible for it has been isolated, scientists can use various methods depending on the desired outcome and the characteristics of the protein. One common method is to use recombinant DNA technology to clone the gene into a suitable vector, such as a bacterial plasmid or a viral vector. This vector can then be introduced into host organisms, such as bacteria, animals, or plants, which will produce the protein using their own cellular machinery.
For example, if the scientist wants to produce the chicken liver protein in bacteria, they can clone the gene into a bacterial plasmid and introduce it into Escherichia coli bacteria. The bacteria will then produce the protein using their own cellular machinery. If a eukaryotic animal host is required for proper processing of the protein, the gene can be cloned into animals like transgenic sheep, goats, chickens, or mice, which have been modified to express recombinant DNA.
The production of the protein can be optimized by manipulating the cloned gene, ensuring continuous production of the desired protein. This is important for commercial purposes or for research purposes.
