Abstract:
This work deals with 3C (Chromosome Conformation Capture) analysis of the chicken alpha-globin gene domain in embryonic erythrocytes and lymphoid cells. Ligation products were quantitatively analyzed by real-time PCR with TaqMan probes. It was found that in lymphoid cells, where alpha-globin gene is not active, the domain has a relatively extended configuration. In embryonic erythrocytes that transcribe alpha(D) and alpha(A) genes, simultaneous interaction of several domain elements was revealed including the major regulatory element, the erythroid-specific DNase I hypersensitive site at a distance of 9 kb upstream from the alpha-globin gene cluster (-9 DHS), promoter of the housekeeping gene CGTHBA, the alpha(D)-globin gene promoter, and the erythroid-specific enhancer located after the alpha-globin gene cluster. We suppose that such interaction is necessary to provide for the active transcription status of the chicken alpha-globin gene domains in erythroid cells.

Chromosome Structure
The centromere is a DNA sequence that links sister chromatids. This is also where kinetochores, protein complexes to which spindle microtubules attach, are constructed after the chromosome is replicated. The kinetochores allow the spindle microtubules to move the chromosomes within the cell during cell division.
Telomeres consist of non-coding repetitive nucleotide...
