Question

A researcher uses generalized transduction to map three bacterial genes. She collects the phage lysates of a donor strain with genotype leu' phe' lys', and uses them to infect a recipient strain that is leur phe lys. Rates of cotransduction for leu are reported. Gene pair leu and phe leu" and lys+ Cotransduction rate 25% | 3% Determine whether phe or lys is physically closest to leu and provide justification O Genes lys and leu are closest because the cotransduction rate of leu and lys' is highest. O Physical distances cannot be determined without the cotransduction rate of lys' and phe" O Genes phe and leu are closest because the cotransduction rate ot phe and lys is lowest. O Genes phe and leu are closest because the cotransduction rate ot leu' and phe'is highest. O Genes lys and leu are dlosest becouse the ootransduction rate of leu' and lys is lowest

Explanation / Answer

The correct option is-

Genes which have high cotransduction frequency will be more closer. The correct option is d. Phe and Leu will be more closes as they have higher cotransduction frequency.
