If an E.coli with heavy DNA is allowed to grow for 80 minutes in a culture medium of N14H4CI, then what would be the proportion of heavy, light and hybrid densities DNA molecule respectively?

Question

If an E.coli with heavy DNA is allowed to grow for 80 minutes in a culture medium of N14H4CI, then what would be the proportion of heavy, light and hybrid densities DNA molecule respectively? (A) (1/16):(2/16):(14/16) (B) (0/16):(14/16):(2/16) (C) (1/16):(14/16):(2/16) (D) (1/8):(2/8):(6/8)

Correct answer is (b) (0/16):(14/16):(2/16)

Q. If an $E . co l i$ with heavy $D N A$ is allowed to grow for $80$ minutes in a culture medium of $N 14 H 4 C I$ , then what would be the proportion of heavy, light and hybrid densities $D N A$ molecule respectively?

$\frac{1}{16} : \frac{2}{16} : \frac{14}{16}$

$\frac{0}{16} : \frac{14}{16} : \frac{2}{16}$

$\frac{1}{16} : \frac{14}{16} : \frac{2}{16}$

$\frac{1}{8} : \frac{2}{8} : \frac{6}{8}$

Correct answer is (b) $\frac{0}{16} : \frac{14}{16} : \frac{2}{16}$
