a) đoạn bổ sung :- X - T - G - X - A - T - G - X - T - A - G - T - X - G -
b) - theo NTBS : A = T = 1500 (nu)
G = X = 2000 (nu)
- chiều dài gen :
L = \(\dfrac{N}{2}.3,4=\dfrac{1500.2+2000.2}{2}.3,4=11900\left(A\right)\)
Chu kỳ xoắn : C = \(\dfrac{N}{20}=\dfrac{1500.2+2000.2}{20}=350\left(chuky\right)\)
