_____ occurs when transcription factors increase rates of transcription.

Explanation:
Transcription factors are proteins that bind to DNA and recruit the transcriptional machinery to boost gene expression. When their action increases the amount of mRNA produced, the gene is up-regulated, meaning the transcription rate is higher in response to signals or conditions. Down-regulation would be a decrease in transcription, silencing is a more permanent shutdown, and amplification refers to increasing gene copy number, not the rate of transcription driven by transcription factors.
