Which statements about the regulation of transcription initiation in these genes are true?

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