Alfred Hershey and Martha Chase made a big contribution in proving DNA role as the hereditary molecule. The experiment is shown in the figure. $\mathrm{A}$ and $\mathrm{C}$ are the presence or absence of radioactivity detected in cells. $\mathrm{B}$ and $\mathrm{D}$ are the presence or absence of radioactivity detected in supernatants cells. Identify $\mathrm{A}, \mathrm{B}, \mathrm{C}$ and $\mathrm{D}$ respectively

The above figure refers to translation. In which of the four options $\mathrm{A}, \mathrm{B}, \mathrm{C}, \mathrm{D}$ and $\mathrm{E}$ are correctly identified

The given diagram illustrates

The adjacent figure represents the structure of basic $30 \mathrm{nm}$ fibre of chromosome of eukaryotes. Choose the correct option in which $\mathrm{F}1, \mathrm{F}2, \mathrm{A}$ and $\mathrm{B}$ are correctly identified

Match the items in Column-I with those in Column-II and choose the correct answer
