What is the function of interchromosomal domains in gene transcription?
 
  A) These domains separate chromosome territories and are areas of active transcription.
  B) These domains act as regions for formation of chiasmata during crossing over.
  C) These domains act as gene-rich regions positioned toward the nuclear membrane to maximize gene transcription.
  D) These domains contain no chromatin and act as channels for the movement of proteins, RNAs, and enzymes among the chromosomal territories.
  E) These domains act as the regions of the chromosome recognized during meiosis when homologous chromosomes are matched up and aligned at the metaphase I plate.
