It was previouslyGenes 2021, 12,The evolutionary conservation of the heterochromatic pattern plus the high degree of sequence identity in the Doc5 fragment duplicated at both sides in the Bari1 cluster prompted us to hypothesize a achievable structural role of the Doc5 sequence both inside the 8 of 17 heterochromatin of D. melanogaster and inside the identity from the h39. It was previously suggested that the preservation of a repetitive non-coding DNA sequence, specifically in the heterochromatin, may be promoted using the help of stabilizing binding proteins [41], such recommended thatproteins. To test this hypothesis, we performed a sequence, specifically in the as chromatin the preservation of a repetitive non-coding DNA One-Hybrid Program assay heterochromatin, could possibly be promoted using the help of stabilizing binding proteins [41], such aimed in the identification of proteins that potentially interact using the Doc5 fragment. as chromatin proteins. To test this hypothesis, we performed a One-Hybrid Method assay The double selection process (i.e., His prototrophy and positivity towards the -galactoaimed in the identification of proteins that potentially interact with the Doc5 fragment. sidase test) applied to determine positive clones ensures that the false positive rate is miniThe double choice approach (i.e., His prototrophy and positivity towards the -galactosidase mized. test) applied to identify optimistic clones guarantees that the false positive rate is minimized.
