A new method of representing DNA sequences which combines ease of visual analysis with machine readability.

abstract：:RNA can directly bind to purine-rich DNA via Hoogsteen base pairing, forming a DNA:RNA triple helical structure that anchors the RNA to specific sequences and allows guiding of transcription regulators to distinct genomic loci. To unravel the prevalence of DNA:RNA triplexes in living cells, we have established a fast ...

abstract：:Three protein isoforms (74, 54 and 42 kDa) are expressed from repressor gene c in the Streptomyces temperate bacteriophage phiC31. Because expression of the two smaller isoforms, 54 and 42 kDa, is sufficient for superinfection immunity, the interaction between these isoforms was studied. The native 42 kDa repressor (N...
