Binucleated cells can be observed using microscopy. Cells must first be fixed to arrest them wherever they are in the cell cycle and to keep their structures from degrading. Their nuclei and tubulin must next be made visible so that binucleation can be identified. DAPI is a dye that binds to DNA and fluoresces blue. For this reason, it is particularly useful at labeling nuclei. Antibody probes can be used t… Web1 day ago · FLAIL is a trans- acting RNA molecule that represses flowering. FLAIL binds to chromatin regions of target genes through conserved sequence motifs. FLAIL interacts with the spliceosome complex to affect target mRNA expression by co-transcriptional alternative splicing process and regulation of chromatin modifications.
