초록

온도 기울기 전기영동장치를 이용하여 d(CXG)와 d(GXC) 염기의 열 안정성을 결정하는데 사람의 $\varepsilon$-글로빈 DNA조각을 사용하였다. 염기 쌍의 안정성은 이웃하는 염기서열에 의한 수소결합과 base stocking 상호작용에 의존한다. 염기 쌍의 안정성은 d(CXG) d(CYG)의 경우에 T.AG.A = A.G>C.T>T.C>C.A>A.C이다.

Human $\varepsilon$-globin DNA fragment was used to determine the thermal stabilities of base pairs at d(CXG) and d(GXC) by Temperature Gradient Gel Electrophoresis(TGGE). The base pair stability depends on the hydrogen bonding interaction and base stacking interaction of neighbor base sequence. The orders of base pair stabilities were T.AG.A = A.G>C.T>T.C>C.A>A.C for d(GXC).d(GYC).
