omeli [17]

Answer:

A. The gene for surface protein was transcribed and translated.

Explanation:

Because all living organisms use the same genetic code, it is possible to express genes from one organism in the other. In this case, the DNA sequence that corresponds to the hepatitis B surface protein gene has been inserted into the banana, and the protein is expressed.

For the protein to be expressed, the gene must have been successfully transcribed into an mRNA by the banana plant machinery. This mRNA has then been translated into a protein that means the hepatitis B surface protein is now present in the cell.
