The upstream area of the chicken alpha-globin gene domain is transcribed in both directions in the same cells.
It was demonstrated previously that in erythroid chicken cells an extended upstream area of the alpha-globin gene domain is transcribed in both directions as a part of ggPRX gene and a part of a full domain transcript of the alpha-globin gene domain. Here, we show that both DNA chains of the above-mentioned region are transcribed in the same cells and that the corresponding transcripts coexist in nuclei. The data obtained suggest that cells possess a molecular mechanism which in some cases prevents the formation of dsRNA and subsequent destruction of both transcripts in spite of the presence of complementary RNA chains in the cell nucleus.
