Question

Giúp mik vs ạ

Answer 1

\(a,\) Vì 2 \(gen\) có chiều dài là như nhau nên số \(nu\) là bằng nhau.

\(\rightarrow L=3,4.\dfrac{N}{2}\rightarrow N=2400\left(nu\right)\)

\(-\) \(Xét\) \(gen\) \(1\)\(( gen\) \(A)\)

\(\rightarrow\left\{{}\begin{matrix}2A+2G=2400\\2A+3G=3120\end{matrix}\right.\rightarrow\left\{{}\begin{matrix}A=T=480\left(nu\right)\\G=X=720\left(nu\right)\end{matrix}\right.\)

\(-\) \(Xét\) \(gen\) \(2\) \((gen\) \(a)\)

\(\rightarrow\left\{{}\begin{matrix}2A+2G=2400\\2A+3G=3240\end{matrix}\right.\rightarrow\left\{{}\begin{matrix}A=T=360\left(nu\right)\\G=X=840\left(nu\right)\end{matrix}\right.\)
