Viral DNA can be inserted into the genome of bacteria by manipulating a specific enzyme known as DNA ligase.
<h3>What is DNA ligase?</h3>
This is a special enzyme found in humans and other forms of DNA. The role of the DNA ligase enzyme is to fuse together distinct strands of DNA. By manipulating this enzyme, scientists have achieved genetic modification.
Therefore, we can confirm that due to the successful manipulation of an enzyme known as DNA ligase, scientists have been able to insert viral DNA into the genome of bacteria.

Answer:
Option D, leaves
Explanation:
The maximum concentration of zinc is accumulated both in the leaves and stem of corn and tobacco plants. But comparatively it is higher in the leaves than in the stem.
Zinc is a micro nutrient as it is required only in a small amount and it is found that plants will lesser zinc concentration dry out easily.
Also the relation between the zinc absorbed is linear to the accumulation of zinc in the leaves. Hence, the higher the zinc absorbed in the corn and tobacco plants, the higher is the zinc accumulating in the leaves.
Hence, option D is correct
