100

The acronym CRISPR stands for this

What is "Clustered Regularly Interspaced Palindromic Repeats"?

100

This is what guides the Cas9 to the target site.

What is guide RNA?

100

This is the type of CRISPR that directly cuts out parts of DNA.

What is CRISPR Cas9-nickase?

200

The organism in which CRISPR DNA sequences were discovered

What is E. coli?

200

This is approximately how long a strand of sgRNA should be.

What is ~20 nucleotides long?

200

This is the type of CRISPR that involves edited epigenetics.

What is CRISPR dCas9-Tet1?

300

This is what the short palindromic repeats separate in bacterial DNA.

What are potentially dangerous viral genes?

300

Cas9 is this type of enzyme that cleaves DNA.

What is an endonuclease?

300
This the type of CRISPR that works using two different gRNAs to guide Cas9 to target, resulting in a double-strand break.

What is CRISPR Cas9-nickase?

400

CRISPR DNA in E. coli is hypothesized to serve this function due to the high content of foreign DNA in its repeats.

What is adaptive immunity in bacteria?

400

This molecule gives the CRISPR-Cas9 system its sequence specificity.

What is gRNA?

400

This is the type of CRISPR that does not alter the DNA, but instead works by demethylating cytosines to allow for transcription.

What is CRISPR dCas9-Tet1?

500

This RNA molecule allows bacteria to recognize and destroy viral DNA using sequence complementarity.

What is CRISPER RNA (crRNA)?

500

This enzyme demethylates cytosines at gene promoters, leading to activation of transcription.

What is Tet1?

500

What molecule and DNA repair process is used to introduce specific nucleotide edits into a genetic sequence?

What is a donor template and Homology-Directed Repair?
