abstract：:Formation of G4 DNA may occur in the course of replication and transcription, and contribute to genomic instability. We have quantitated abundance of G4 motifs and potential for G4 DNA formation of the nontemplate strand of 5' exons and introns of transcripts of human genes. We find that, for all human genes, G4 motif...
