Given below is the restriction site of a restriction endonuclease Pst I and the cleavage sites on a DNA molecule. \[\begin{aligned} & 5^{\prime} \mathrm{C}-\mathrm{T}-\mathrm{G}-\mathrm{C}-\mathrm{A} \overset{\pmb{\downarrow}}{-} \mathrm{G} 3^{\prime} \\ & 3^{\prime} \mathrm{G} \underset{\pmb{\uparrow}}{-} \mathrm{A}-\mathrm{C}-\mathrm{G}-\mathrm{T}-\mathrm{C} 5^{\prime} \end{aligned} \] Choose the option that gives the correct resultant fragments
Official answer
(D)
\[\begin{array}{lr} 5^{\prime} \mathrm{C}-\mathrm{T}-\mathrm{G}-\mathrm{C}-\mathrm{A} & \mathrm{G} 3^{\prime} \\ 3^{\prime} \mathrm{G} & \mathrm{~A}-\mathrm{C}-\mathrm{G}-\mathrm{T}-\mathrm{C} 5^{\prime} \end{array} \]
