Câu 1
a. L = \(\dfrac{N}{2}.3,4\Rightarrow N=\dfrac{2L}{3,4}=\dfrac{2.4080}{3,4}=2400\left(Nu\right)\)
A = T = 500 (Nu)
G = X = \(\dfrac{2400-2.500}{2}=700\left(Nu\right)\)
b. Chu kì xoắn của gen A:
Sx = \(\dfrac{2400}{20}\) = 120 (CK)
Câu 2
L = \(\dfrac{N}{2}.3,4\Rightarrow N=\dfrac{2L}{3,4}=\dfrac{2.3060}{3,4}=1800\left(Nu\right)\)
A = T = 1800.30% = 540 (Nu)
G = X = \(\dfrac{1800-2.540}{2}=360\left(Nu\right)\)
