What is a primary commercial application of CRISPR-Cas9 technology in the agricultural sector?
CRISPR-Cas9 lets scientists change a plant’s DNA in a precise way. Other options are incorrect because People think editing genes cuts fertilizer cost...
What are the ethical implications of using CRISPR-Cas9 technology in gene therapy, particularly concerning genetic modifications in humans?
The main ethical issue is that editing human genes can create 'designer babies' and cause unknown long-term effects. Other options are incorrect becau...
How can CRISPR-Cas9 technology impact the biopharmaceutical industry in terms of drug development?
CRISPR-Cas9 can cut DNA at a chosen spot. Other options are incorrect because People think CRISPR makes research more expensive, but the tool actually...
Which of the following statements best describes the implications of patent issues surrounding the CRISPR-Cas9 technology in the field of medicine?
Patent disputes can block or slow the creation of new medical treatments that use CRISPR-Cas9. Other options are incorrect because Some think a natura...
How do regulatory challenges impact the commercialization of CRISPR-Cas9 technology in agricultural biotechnology, especially concerning the design of guide RNA?
Regulatory rules can be unclear or change, which makes companies unsure about what is allowed. Other options are incorrect because People sometimes th...
Arrange the following steps in the CRISPR-Cas9 genome editing process in the correct order: A) The guide RNA binds to the target DNA sequence, B) Cas9 protein creates a double-strand break in the DNA, C) The cell's repair mechanisms are activated, D) The desired genetic modification is introduced during repair.
The guide RNA first finds and sticks to the DNA that matches its sequence. Other options are incorrect because This option says Cas9 cuts before the g...
If CRISPR-Cas9 successfully edits a gene to confer antibiotic resistance in bacteria, what is the most likely underlying mechanism that enables this change?
The guide RNA is made to match a specific DNA sequence. Other options are incorrect because Some think Cas9 changes DNA everywhere; The PAM site is a ...
Which of the following applications of CRISPR-Cas9 best exemplifies its use in agriculture?
CRISPR-Cas9 cuts a plant’s DNA at a chosen spot. Other options are incorrect because Many think CRISPR is only for medicine; CRISPR is not used to mak...
A farmer wants to improve the drought resistance of a crop using CRISPR-Cas9 technology. Which of the following statements best describes how CRISPR-Cas9 could be applied in this scenario?
CRISPR-Cas9 can cut DNA at a chosen spot and remove a harmful gene. Other options are incorrect because Some think CRISPR only adds new genes; People ...
How does the CRISPR-Cas9 system achieve precise genome editing?
The system uses a guide RNA, a short RNA strand that matches a specific DNA sequence, to direct the Cas9 protein to that spot. Other options are incor...
CRISPR-Cas9 : Genetic Editing :: RNA Polymerase : ?
RNA Polymerase reads DNA and builds a matching RNA strand. Other options are incorrect because Protein synthesis is the whole process that turns RNA i...
In CRISPR-Cas9 genome editing, the Cas9 protein acts as molecular scissors that cut DNA at specific sites, guided by a sequence known as __________.
Protospacer is the short RNA piece that matches the DNA target. Other options are incorrect because A promoter starts the copying of DNA into RNA, but...
Which of the following statements about CRISPR-Cas9 Genome Editing are true? Select all that apply.
CRISPR-Cas9 lets scientists cut and replace DNA at a chosen spot, so it can fix or change genes exactly. Other options are incorrect because Cas9 is n...
In CRISPR-Cas9 genome editing, how does the specificity of the Cas9 protein influence the success of gene editing?
The Cas9 protein looks for a short DNA tag called a PAM (protospacer adjacent motif). Other options are incorrect because The guide RNA tells Cas9 whe...
