9 Required information Read the overview and complete the interactivities that follow Cotransduction can be used to map bacteria genes. A small portion of the bacterial chromosome is taken up by a bacteriophage and transferred to a new bacterium upon subsequent infection. The following questions deal with cotransduction. Part 3 of7 Read the report and answer all questions. Results Selected Nonselected genemedium Number of colonies that grew on Cotransduction +arginine arginine 21 0.42 P1 phage can package up to 5% of the E. coli chromosome into each phage True or False True False

Explanation / Answer

Contransduction frequency is defined as the ratio of transductants that has co-inherited both the markers divided by total number of transductants.

9) The P1 phage can pack only 1% of E.coli chromosome. So, the statement is false.

10) The definition corresponds to contransduction. So, the given statement is true.
