Secondary dna structure
WebIn view of the differences of the X-ray diffraction patterns for DNA fibers at 66 and 92 per cent relative humidities, it is proposed that the secondary structure of DNA consists of two partially intercalated double helices at 92 per cent. Possible biological implications are discussed. Continue Reading VIEW PDF Download PDF WebThe other common type of secondary structure is the beta strand. A Beta strand (β-strand) is a stretch of polypeptide chain, typically 3 to 10 amino acids long, with its backbone in an almost fully extended conformation. Two or more parallel or anti-parallel adjacent polypeptide chains of beta strand stabilised by hydrogen bonds form a beta ...
