Answer:
it is located 1000 nucleotides upstream of the gene’s core promoter - true
it is located 1000 nucleotides downstream of the gene’s core promoter- true
it is in the gene’s coding region - False
Explanation:
These enhancers are located 50 or more kilobases from the promoter they controlled upstream from a promoter, downstream from a promoter within an intron, or even downstream from the <u>final exon</u> of a gene which can be thousands of bp away from the gene's core promoter and can also occur thousands of nucleotides away from the gene's core promoter needing the activity of a DNA -bending protein that binds to the enhancer changing the shape of the DNA and allow interactions between the activators and transcription factors.
