DNA is the correct answer but next time put answer choices so that people can better answer your questions. Thanks!
The right answer for the question that is being asked and shown above is that:
The density of a certain object can be solved using two parameters: The mass and the volume.
Density = mass / volume.
So, from the given question, we are lacking on what the volume is.
Some people may develop redness and burning discomfort in the vicinity of the bandage if they are allergic to eugenol.
- In order to lower the danger of surgery site infection and bleeding, speed up wound healing, and lessen patients' pain and discomfort, periodontal dressings were devised.
- The ability of eugenol-based dressings to numb pain and make sites less sensitive made them popular in the past, especially after gingivectomy.
- Based on its antibacterial qualities, zinc oxide-eugenol dressings appeared to prevent or delay bacterial development. However, it was discovered that eugenol irritated oral mucosal tissues, caused allergic reactions, and caused tissue necrosis, especially in bone, which slowed the healing process.
- Thus, noneugenol periodontal surgical dressing are preferred.

Answer:
tetracycline
Explanation:
When the DNA insert is ligated in Pstl site, the ampicillin gene is disrupted while <em>tetracycline gene is still intact</em>.
- If the bacterial colony is growth in a medium with only ampicillin, only the cells that contains the plasmid with the insert will grow.
- If the bacterial colony is growth in a medium with only tetracycline, the cells which have incorporated the plasmid will survive. We cannot distinguish between cells with plasmid + insert and plasmid alone.
- If the bacterial colony is growth in a plate with ampicillin + tetracyclin, only the cells with the plasmid without the insert will grow.
Therefore, to ensure that the cells of a bacterial colony contains the plasmid, they have to be seeded in a plate with tetracycline.
