question 21

Multiple Choice

A transformation experiment is performed with a donor strain that is resistant to four drugs: A, B, C, and D determined by genes A, B, C, and D. The recipient strain is sensitive to all four drugs. The treated recipient-cell population is divided up and plated on media containing various combinations of the drugs. A cell that is resistant to the added drug(s) will form a colony. The table below shows the results. $$\begin{array} { l l l l } \text { Drug(s) Added } & \text { Number of Colonies } & \text { Drug(s) Added } & \text { Number of Colonies } \\\hline \text { None } & 10,000 & \mathrm { BC } & 51 \\\text { A } & 1,156 & \mathrm { BD } & 49 \\\text { B } & 1,148 & \mathrm { CD } & 786 \\\text { C } & 1,161 & \mathrm { ABC } & 30 \\\text { D } & 1,139 & \mathrm { ABD } & 42 \\\text { AB } & 46 & \mathrm { ACD } & 630 \\\text { AC } & 640 & \mathrm { BCD } & 36 \\\text { AD } & 942 & \text { ABCD } & 30\end{array}$$ One of the genes is quite distant from the other three that are tightly linked.
