Both restriction enzymes and CRISPR-Cas9 were isolated from what organisms and what was their
“job” in those organisms?
Homework Answers
CRISPR-Cas9 were isolated from genomes of prokaryotic organisms like bacteria and archaea.
Their job was to detect and identify and destroy DNA from same type of Bacteriophages during subsequent infections. Therefore these enzymes play an important role against viral infections.

A number of advances have been made in biotechnology.
CRISPR/Cas9 one of the most controversial, and is getting a lot of
current media attention. It is a method by which scientists can
precisely edit DNA sequences at exact locations. Benefits obviously
include the potential to “repair” mutated genes that cause disease.
In fact, preliminary results from one of the earliest clinical
trials of CRISPR/Cas9 provide evidence that the technique is safe
and feasible to use for treating human diseases. What...

4. The CRISPR-Cas9 system is an important new technique in
molecular biology. What is the natural function of this system?
Describe how you would use this system to generate a null mutation
in another organism (i.e. explain Figure 6-43). How does it work?
What is the modification of the method that allows for correction
of a mutation (e.g. the mouse crystalline gene)? And lastly, what
are the problems with the CRISPR system?
