Answer :
To explain why the gene of a frog may be inserted into a bacterial chromosome, one possible reason is to utilize bacteria as a host for gene expression. This can be achieved through the following steps:
1. Bacteria are often used in genetic engineering because they have simple and well-understood genetic structures, making it easier to manipulate their DNA.
2. By inserting a frog gene into a bacterial chromosome, scientists can take advantage of the bacteria's rapid growth and replication rate to produce large quantities of the gene product.
3. Bacteria can serve as "factories" for producing proteins encoded by the inserted frog gene, which can be used for various purposes such as medical research, pharmaceutical production, or biotechnology applications.
4. Additionally, the inserted frog gene can be engineered to express specific traits or characteristics in the bacteria, allowing researchers to study the gene's function in a controlled environment.
Overall, inserting a frog gene into a bacterial chromosome provides a practical and efficient way to study, produce, or manipulate specific genes for scientific or commercial purposes.
