'''LOW-TEMPERATURE STUDY OF THE A-DNA FRAGMENT D(GGGCGCCC)'''
===LOW-TEMPERATURE STUDY OF THE A-DNA FRAGMENT D(GGGCGCCC)===




==Overview==
<!--
The structure of the A-type duplex d(GGGCGCCC) was determined from data measured at 115 K to 2.0 A resolution. The space group, P4(3)2(1)2, is the same as for the 293 K structure; cell dimensions are a = 42.74 (4), c = 24.57 (1) A; R = 0.21 for 1694 observed reflections. The conformation and hydration are similar at the two temperatures. The average displacement parameters (B) for bases, sugars and phosphates all decrease by about 9 A2 relative to those found at 293 K. The individual values of B1/2 are linearly related to the distance from the molecular center of mass.
The line below this paragraph, {{ABSTRACT_PUBMED_3271557}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 3271557 is the PubMed ID number.
