Structure of the tetradecanucleotide d(CCCCGGTACCGGGG)₂ as an A-DNA duplex

The crystal structure of the tetradecanucleotide sequence d(CCCCGGTACCGGGG)₂ as an A-DNA duplex and its interaction with a manganese ion are described.

Interactions of Mn²⁺ with a non-self-complementary Z-type DNA duplex

Crystal structures of the hexanucleotide d(CACGCG)·d(CGCGTG) were determined in the presence of Mn²⁺ ions in two crystal lattices and provide insights into ion interactions.
