| 摘要 |
The present invention provides a double-stranded nucleic acid in which at least one nucleic acid strand includes an unnatural base that forms a self-complementary base pair or an unnatural base that forms a base pair with any natural base with substantially the same thermal stability. The present invention also provides a method of hybridizing a first nucleic acid strand with a second nucleic acid strand, wherein the first nucleic acid strand includes an unnatural base that forms a self-complementary base pair or an unnatural base that forms a base pair with any natural base with substantially the same thermal stability, and a method of applying the nucleic acid to SNP detection, a DNA chip, DNA/RNA computing, or an in vitro translation system. The present invention provides a method of introducing an unnatural base into a nucleic acid strand and thereby controlling the thermodynamic stability in hybridization of the nucleic acid strand. |
