Answer:

The correct answer will be- the advancement in the technology

Explanation:

The atomic theory which suggested that atom is the smallest and indestructible form was proposed by the John Dalton in 1803.   Later the atomic theory was modified with the discovery of the sub-atomic particles like electrons, protons and neutrons.

This modification in the theory is the result of the advancement in the technology which provided new evidence of the atomic models which represented the distribution of the sub-atomic particles in the atom.

Thus, the advancement in technology is the correct answer.

bogdanovich [222]

If mutation destroys the function of the Cas9 gene then the bacteria will not be able to target a specific bacteriophage for destruction upon infection for the second time.

<h3>What is the Cas9 gene?</h3>
  • Cas9 is a 160 kilodalton protein that plays a vital role in the immunological defense of certain bacteria against DNA viruses and plasmids and is heavily utilized in genetic engineering applications.
  • Its main function is to cut DNA and thereby alter a cell's genome.
  • Although Cas9 is an endonuclease and is evolved as a mechanism of immunity against viruses, they are not considered restriction enzymes.
