The diagram below shows two stretches of DNA in the genome of an
imaginary eukaryotic cell. The top stretch of DNA includes the
fantasin gene, along with its promoter and one of its enhancers.
The bottom stretch of DNA includes the imaginin gene, its promoter,
and one of its enhancers. The slash marks (//) indicate that more
than 1,000 nucleotides separate the promoter and enhancer of each
gene

Which statements about the regulation of transcription
initiation in these genes are true?
Select all that apply.

1) Control elements A, B, and C are proximal control elements
for the fantasin gene.
2) The fantasin gene and the imaginin gene have identical
enhancers.
3) Both the fantasin gene and the imaginin gene will be transcribed
at high levels when activators specific for control elements A, B,
C, D, and E are present in the cell.
4) Control elements C, D, and E are distal control elements for the
imaginin gene.
5) The imaginin gene will be transcribed at a high level when
repressors specific for the imaginin gene are present in the
cell.
6) The fantasin gene will be transcribed at a high level when
activators specific for control elements A, B, and C are present in
the cell.
7) Both the fantasin gene and the imaginin gene will be transcribed
at high levels whenever general transcription factors are present
in the cell.
