What would happen if the Cas9 part of CRISPR-Cas9 wasn't functional? Would CRISPR be as effective?
What would happen if the Cas9 part of CRISPR-Cas9 wasn't functional? Would CRISPR be as effective?
Homework Answers
Answer: No
Explanation:
Cas9 is an RNA guided DNA endonuclease. It recognizes a specific
DNA sequence and cleaves it.
The target specificity is attained through the complementary
sequence of the guide RNA.
dCas9 is an endonuclease deficient Cas9 that is used for
transcriptional gene sl=ilencing of specific genes.

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?

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...

You wish to edit a gene in a population of stem cells using CRISPR/Cas9. You design a plasmid and transfect it into the cells. Your plasmid included the guide RNA sequence with promoter, the Cas9 gene inserted between an appropriate promoter and termination sequence, and the usual Origin of Replication and Resistance/Marker gene. However, instead of being edited, your target gene is silenced and its protein is not produced at all. What is the most likely explanation? The cells have...
