Answer:
The promoter region/sequence
Explanation:
Promoter sequences/region is where the transcription factors and RNA polymerase must attach before the gene can be transcribed. SO if we mutate this sequence, the transcription factors and RNA polymerase won't recognize it thus would not attach and transcribe the targeted gene.
If your decreasing the size of something spinning your also decreasing the amount it spins so it would be spinning slower !
