What does it mean to say that a signal is transduced?

#SCPH28 | Zoology

  1. The signal enters the cell directly and binds to a receptor inside.

  2. The physical form of the signal changes as it passes from the cell membrane to the ultimate intracellular target.

  3. The signal is amplified, such that even one signal molecule evokes a large response.

  4. The signal triggers a sequence of phosphorylation events inside the cell.

To express a yeast gene in E. coli, your task is to design a strategy to insert the yeast gene into the bacterial plasmid. Below is a map of the area of the yeast genome surrounding the gene in which you are interested.

 
The distance between each tick mark placed on the line above is 100 bases in length
Below are the enzymes you can use, with their specific cut sites shown 5’-XXXXXX-3’ 3’-XXXXXX-5’

 
The plasmid is 5,000 bases long and the two farthest restriction enzyme sites are 200 bases apart. The plasmid has an ampicillin resistance gene somewhere on the plasmid distal from the restriction cut sites.

                              
Which of the following restriction enzyme is the best choice for you use to design a way to get the insert into the vector?
