B: A+G=54%
C: A+G=46%
D: T+C=60%
E: A+T=46%
A: T+C=46%
B: A+G=54%
C: A+G=46%
D: T+C=60%
E: A+T=46%
举一反三
- 某双链DNA中已知一条链中A=30%、G=24%,下列其互补链的碱基组成正确的是() A: T+C=46% B: A+G=54% C: A+G=46% D: T+C=60% E: A+T=46%
- 某双链DNA中已知一条链中A=30%,G=24%,其互补链的碱基组成,下列哪一项是正确的: A: T+C=46% B: A+G=54% C: A+G=46% D: T+C=60% E: T+C=54%
- 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)= ?
- 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)= ?
- 已知某DNA的一条链中A=30%,G=24%,其互补链的碱基组成是:(<br/>) A: T和C为46% B: C和G为46% C: A和G为54% D: T和C为54% E: T和C为60%
