![Enhancer RPA Gene A
Use the diagram above, which depicts a chromosomal region less than 500,000 bp, to determine the
expression of each gene under the scenarios specified in the table. Regulatory promoters are
indicated by "RP". Genes A, B, and C have intermediate expression when no regulatory proteins are
bound. Complete the table by choosing high, intermediate, or low to describe the expression level of
each gene under each specified scenario (i and ii).
