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

Which of the following might decrease the transcription of all genes in a bacterial cell? Select one: a. a decrease in the amount of sigma factor b. a decrease in the amount of RNA polymerase II c. a mutation that introduced extensive sequence changes into the DNA that precedes a single gene’s transcription start site d. a mutation that introduces a stop codon into the DNA that precedes the gene’s coding sequence

<Problem Set 9a Question 4 4 of 5 > Part A - TUA: Uverview UUR HIDRL yur g pruun When scientists use CRISPR-Cas9 to make specific cuts to a genome, they have a goal they're trying to achieve. Ohen, they either want to modify the protein that a particular gene encodes, or they want to block production of a particular protein. Depending on the goal, they customize the SANA they insert into the cell. For the CRISPR-Cas9 system to modify...

PLEASE ANSWER ALL THE QUESTIONS: 1.What is true of tRNA (transfer RNA)? A they contain an anti-codon B they carry an amino acid C they can interpret the genetic code D all of these are true 2. How can transcription factors bound to distant enhancers influence gene expression? A the transcription factors can slide along the DNA until they get to the gene's promoter B DNA can loop, bringing these proteins into contact with the gene's promoter C both of...
