Most of the enzymes used as molecular scissors are known as restriction enzymes. What is the reason for this name?
kicyunya [14]
Because when you put a part of the DNA and take it out, you can restrict an ability of that cell. When you cut out a piece of DNA from a pancreas beta cell that codes for insulin synthesis, you restrict the cells ability to make insulin, hence the name "restriction enzyme". I hope this is the answer that you are looking for and it comes to your help.
