Câu 2: Một gen có X = 1050 nucleotit chiếm 35% tổng số nucleotit của gen.

a. Tính số nucleotit từng loại của gen.

b. Tính khối lượng phân tử của gen.

c. Tính số liên kết hidro của gen. 

a. Tổng số nucleotit của gen:

N = (1050 x 100) : 35 = 3000 nu

* Số nu từng loại:

 A = T = (3000 : 2) – 1050 = 450 nu

G = X = 1050 nu  

b. Khối lượng:

 M = N . 300 = 3000 x 300 = 900000 đvc

c. Số liên kết hidro: H = 2A + 3G = 2 . 450 + 3 . 1050 = 4050
