Question 1: The sequence in the entry that was obtained from sequencing a piece of DNA from Vibrio fischeri genomic DNA digested with Sal I is 8654 bp long. Question 2: The -10 sequence for the lux operon is tgttata. 2 nucleotides are different when compared to the ideal sequence. Question 3: The lux R has its own promoter and is transcribed in the opposite direction from the lux operon‚ so it cannot be transcribed from the same strand because the RNA Polymerase recognizes promoter sequences

1. For this experiment‚ what were the independent variable and the dependent variable? What were the constants? The environmental factors that you are testing on the rate of transpiration are the independent variable of this experiment. These independent variables are specifically light‚ fan‚ dark‚ and humidity. The dependent variable is the rate of transportation because this depends on whatever environmental factor the plant is placed. The constants are things like the type of plant used‚ room
