The genetic code is universal across organisms.This feature is advantageous in the process of:

Explanation

The correct answer is synthesis of insulin from bacteria. The universality of the genetic code means that the same codons code for the same amino acids across different organisms. This allows a gene from one organism, such as the human insulin gene, to be inserted into another organism, such as a bacterium, and be expressed correctly. This is the basis for producing human insulin in bacteria, which is a common practice in biotechnology.Other options are incorrect because they do not rely on the universality of the genetic code. Karyotyping is a method for organizing and studying chromosomes, gene amplification is a technique to increase gene copies, and gene isolation is a basic molecular biology procedure. None of these directly benefit from the genetic code being universal.
