c) What is the map distance between e and ss?
14 map units [(122+18)/1000] 2) You want to perform an interrupted mating mapping experiment with a Hfr strain that
is Pyr+, Met+, Xyl+, Tyr+, Arg+, His+, Mal+, and StrS.
a) What would be an appropriate F- bacterial strain to use as the other partner in this
Pyr-, Met-, Xyl-, Tyr-, Arg-, His-, Mal-, StrR
b) In this interrupted mating experiment, the Pyr+ gene enters the recipient in 5 minutes.
However, at this time point there are no resulting colonies that are Met+, Xyl+, Tyr+,
Arg+, His+, or Mal+. Af...
