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.

Answer:
Explanation:
The line graph illustrates the temperatures in London, New York and Sydney on monthly average and the table introduces the information about the annual hours of sunshine for these cities. The overall view is that London is always exceeded by the rest in both the temperature and the number of sunshine hours.
To specify, the line graph shows that in New York, the average temperature goes up slightly from 4.5 degree in January to 8 degree in March, before a more significant increase to the highest of 30 degree in July, followed by a drop to 5 degree in December. Similarly, in London, after climbing gradually from the lowest point of 9 degree to the highest of 23 degree in July, the figure stays unchanged in the next month and then fall to 9.5 degree in December.
On the contrary, in Sydney, the temperature decrease insignificantly from 25.5 degree in January to the lowest of 16 degree in July, before a gradual rise to 25 degree in December. Meanwhile, the table indicates that New York has the largest number of sunshine hours per year with 2535 hours, came after by Sydney and London with 2473 hours and 1180 hours respectively.
In conclusion, London is likely to be the coldest city because its annual hours of sunshine is less than two others.
