a) N = Cx 20 = 180 x 20 = 3600 (nu)

l = N x 3,4 : 2 =6120 A^o

b) A - G = 20% 

A + G= 50%

=> A = T = 35% N = 1260 (nu)

 G= X = 15%N = 540 (nu)

a) 

\(L=C.34=180.34=6120\left(^oA\right)\)

b) \(N=20.C=20.180=3600\left(nu\right)\)

⇒ \(20\%N=720\left(nu\right)\)

Theo bài ta có hệ : 

\(\left\{{}\begin{matrix}A-G=720\\2A+2G=3600\end{matrix}\right.\)

⇒ \(\left\{{}\begin{matrix}A=1260\left(nu\right)\\G=540\left(nu\right)\end{matrix}\right.\)

a) N = Cx 20 = 180 x 20 = 3600 (nu)

l = N x 3,4 : 2 =6120 A^o

b) A - G = 20% 

A + G= 50%

=> A = T = 35% N = 1260 (nu)

 G= X = 15%N = 540 (nu)

a) \(C=\dfrac{N}{20}=\dfrac{18000}{20}=900\) (chu kì)

b) Ta có:

\(A=T=360\left(nu\right)\)

⇒ \(G=X=\dfrac{N}{2}-A=\dfrac{18000}{2}-360=8640\left(nu\right)\)

a) C = N / 20 = 900 (chu kì)

b) A = T = 360 (nu)

G= X = N/2 - A = 8640 (nu)

a) N = C x 20 = 2400 nu

l = N x 3,4 : 2 =4080 A^o

b) A - G = 20% ; A + G = 50%

=> A = T = 35%N = 840 nu

   G = X = 15%N = 360 nu

Lần sau gõ latex cho rõ nhìn bạn nha!

\(a,N=2A+2X=1904\left(nu\right)\)

\(L=\dfrac{2L}{2,4}=1120\left(\overset{o}{A}\right)\)

\(C=\dfrac{N}{20}=95\)

\(b,A=T=320\left(nu\right)\)

\(X=G=632\left(nu\right)\)

\(a,L=34C=34.150=5100\left(A^o\right)=510\left(nm\right)\\ b,N=20C=20.150=3000\left(Nu\right)\\ A=T=1500\left(Nu\right)\\ G=X=0\)

$a,$ \(N=2T+2G=3400\left(nu\right)\)

$b,$ \(L=3,4.\dfrac{N}{2}=5780\left(\overset{o}{A}\right)\)

$c,$ \(H=2T+3G=4300\left(lk\right)\)

$d,$ Số ADN con là: \(2^5=32\left(ADN\right)\)

$e,$ \(N_{mt}=N.\left(2^5-1\right)=105400\left(nu\right)\)
