I’m not sure if this is the right answer but the doctor would continue you to take it the few days after you have been feeling better to ensure the bacterial infection is completely gone?

Answer:
T-A-C-T-G
Explanation:
Deoxyribonucleic acid, widely known as DNA, is the genetic material in living cells. It is a double-stranded molecule, with each strand arising from the pair of nucleotide monomers that forms its structure. In the DNA, four nucleotides exist namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
These four bases occur in different combinations to form a sequence that makes up each strand of the DNA. However, each nucleotide pairs with one another using the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine will always hydrogen bond with Thymine, while Guanine will always hydrogen bond with Cytosine i.e. A-T, G-C.
Based on the above, a DNA strand with sequence: A-T-G-A-C will pair with another DNA strand with sequence: T-A-C-T-G.
Somatic mutations are acquired after birth in non-reproductive cells. These changes occur in only certain cells of the body and can be caused by tobacco use, ultraviolet radiation, viruses, chemicals and age. Acquired mutations are the most common cause of cancer.
Humans experience many somatic mutations over a lifetime, and the human body is normally able to correct most of these changes. This is why there is only a small chance of one mutation causing cancer. It normally takes many mutations over a lifetime to cause cancer. This is why older people are the most likely group to get cancer, as they have had more chances for mutations to build up.
