Formation of parallel four-stranded complexes by guanine-rich motifs in DNA and its implications for meiosis
"We have discovered that single-stranded DNA containing short guanine-rich motifs will self-associate at physiological salt concentrations to make four-stranded structures in which the strands run in parallel fashion. We believe these complexes are held together by guanines bonded to each other by Hoogsteen pairing. Such guanine-rich sequences occur in immunoglobulin switch regions1, in gene promoters2,3, and in chromosomal telomeres4.
I'm studying for PhD plant biotechnology exam. This book would be a great help. Maybe someone have a pdf file?
The effects of natural variation in background radioactivity on humans, animals and other organisms.
Who can me give access to this study:
If anyone has this paper it could be very helpful.

I'm also searching for this one:
