How does gene cloning primarily operate?

• A. By altering the structure of proteins
• B. By isolating and making copies of a gene
• C. By combining genes from different organisms
• D. By editing the genome of living organisms

Answer: (B)

Gene cloning primarily operates by isolating and making copies of a specific gene. This process involves several key steps, which include extracting the DNA containing the gene of interest, using enzymes to cut out that gene, and then inserting it into a vector (like a plasmid). The vector can then be introduced into a host cell, where it replicates along with the cell’s own DNA. As the host cell divides, it creates numerous copies of the gene, thus amplifying the original sequence. This method is crucial in biotechnology for various applications, such as producing proteins, creating genetically modified organisms, or studying gene function and regulation. The focus is on acquiring a specific gene and reinforcing its presence through replication, making understanding the mechanics of isolation and copying essential in the field of genetic engineering.
