The ability to transfer genes from one organism to another is due to the universal nature of genetic code. Here are the steps explaining why and how it happens:

1. Universality of Genetic Code: All living organisms share the same genetic code. This means that the sequence of nucleotides in DNA and RNA, and the sequence of amino acids in proteins, is interpreted in the same way in all organisms. This universality allows genes to be read and transcribed into proteins in the same way, regardless of the organism.

2. DNA Extraction: The first step in transferring a gene from one organism to another is to extract the DNA from the organism that contains the desired gene. This is usually done by breaking down the cell and nuclear membranes using a combination of physical and chemical methods.

3. Identification and Isolation of the Desired Gene: Once the DNA has been extracted, the desired gene must be identified and isolated. This is often done using restriction enzymes, which are proteins that can cut DNA at specific sequences.

4. Insertion of the Gene into a Vector: The isolated gene is then inserted into a vector, which is usually a plasmid or a virus. The vector is used to transport the gene into the target organism.

5. Transformation or Transfection: The vector containing the desired gene is then introduced into the target organism. This process is known as transformation or transfection. If the process is successful, the target organism will now contain the desired gene.

6. Expression of the Gene: Once the gene is inside the target organism, it can be expressed, meaning it can be transcribed and translated to produce the desired protein.

This process, known as genetic engineering or recombinant DNA technology, has a wide range of applications, from the production of insulin for diabetes treatment to the creation of genetically modified crops.
