There are three principles to keep in mind when predicting the sequence of the mRNA produced by transcription of a particular DNA sequence.
The RNA polymerase reads the sequence of DNA bases from only one of the two strands of DNA: the template strand.The RNA polymerase reads the code from the template strand in the 3' to 5' direction and thus produces the mRNA strand in the 5' to 3' direction.In RNA, the base uracil (U) replaces the DNA base thymine (T). Thus the base-pairing rules in transcription are A→U, T→A, C→G, and G→C, where the first base is the coding base in the template strand of the DNA and the second base is the base that is added to the growing mRNA strand.</span>

Answer:

Decrease the effectiveness of this process.

Explanation:

Resistance emerges is an essential part of this process because this resistance causes decrease in the effectiveness of the drugs. If this resistance is not a part of this process, the microbes get resistance from the drugs which  leads to lower the effectiveness of antimicrobial disease or infection so that's why resistance is considered as the essential part of this process of project.
