举一反三
- 一双链DNA分子,若一条链中(A+G)/(C+T)=0.7,求:①互补链中(A+G)/(C+T)=?②整个DNA分子中(A+G)/(C+T)=?
- 对一双链DNA而言,若一条链中(A+G)/(T+C)= 0.7,则: (1)互补链中(A+G)/(T+C)= ? (2)在整个DNA分子中(A+G)/(T+C)= ? (3)若一条链中(A+ T)/(G +C)= 0.7,则互补链中(A+ T)/(G +C)= ? (4)在整个DNA分子中(A+ T)/(G +C)= ?
- 对一双链DNA而言,若一条链中(A+G)/(T+C)=0.4,则:(1)互补链中(A+G)/(T+C)= ?(2)在整个DNA分子中(A+G)/(T+C)= ?(3)若一条链中(A+ T)/(G +C)= 0.6,则互补链中(A+ T)/(G +C)= ?
- 一双链DNA分子,若一条链中(A G)/(C T)=0.7,求:__①互补链中(A G)/(C T)=?__②整个DNA分子中(A G)/(C T)=?
- DNA分子中的碱基组成是( ) A: A+G=C+T B: C=G,A=T C: C+G=A+T D: A=G
