Illustration of sexduction in E. coli using streptomycin resistant F-lac- recipients and F′lac+ donors Abstract The process in which DNA from a donor cell is transferred through physical contact into a recipient cell is known as conjugation. In the experiment, sexduction, a cross between F′ and F- plasmids, was demonstrated by mixing the donor and recipient, diluting them and using selective plating methods. The plasmids from the donor, recipient and transconjugant were isolated and analyzed…

The first step of the experiment was to prepare the 2M HCl solution for Part A. 200 mL of deionized water was placed into a 600 mL and then 100 mL of 6M HCl was added to dilute the acid. 100 mL of 3M NaOH and 50 mL of deionized water were then combined to form 150 mL of a 2M NaOH solution. The Lab quest then had to be set up so that the temperature changes taking place in the coffee cup calorimeter could be recorded. The temperature probe was plugged in and the “Time Based” data collection…

2.1 Test materials: The essential oils of Curcuma longa (Zingiberaceae) rhizomes, Pogostemon heyneanus (Lamiaceae) leaves and Zanthoxylum limonella (Rutaceae) fruits were obtained from a commercial oil extraction plant in Assam, India.
