Answer:
Promoter Strength
Step-by-step explanation:
A promoter is a DNA sequence that can recruit transcriptional machinery and the sequence promoter is what determines the strength of the promoter ( a strong promoter leads to a high rate of transcription initiation).In regards to mRNA stability, the promoter strength can be tuned to increase the gene expression by producing more quantities of the mRNA. The tuning of promoter strength is based on efficient promoter recognition and rapid binding of the DNA polymerase.
