which statements about the regulation of transcription initiation in these genes are true? select all that apply. view available hint(s)for part b 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. the figure 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 its enhancers a, b, and c. the bottom stretch of dna includes the imaginin gene, its promoter, and its enhancers d, e, and c. enhancers are control elements. which statements about the regulation of transcription initiation in these genes are true?select all that apply. both the fantasin gene and the imaginin gene will be transcribed at high levels whenever general transcription factors are present in the cell. the fantasin gene and the imaginin gene have identical enhancers. 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. 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. control elements a, b, and c are proximal control elements for the fantasin gene. the imaginin gene will be transcribed at a high level when repressors specific for the imaginin gene are present in the cell. control elements c, d, and e are distal control elements for the imaginin gene.

Respuesta :

The statements are true about the regulation of transcription initiation in these genes:

  • Both the fantasin and imaginin genes are transcribed at high levels when specific activators for control elements A, B, C, D, and E are present in the cell.
  • Control elements C, D, and E are the distal control elements for imaginin genes.
  • Fantasin genes are transcribed at high levels when specific activators for control elements A, B, and C are present in the cell.

Only certain genes are ever transcribed in eukaryotic cells. The regulation of transcription initiation depends on the interaction of specific transcription factors with specific regulatory elements on enhancers.

In the imaginary eukaryotic cell used as an example here, the enhancers of the fantasin gene and the imaginin gene are unique in that they contain different control elements (A, B, and C for the fantasin gene; C, D, and E for the shade of a gene). Any gene will be transcribed at a high level if the cell has specific activators for all the regulatory elements in its enhancer.
