Question

what are the two main components of crispr technology?
□ an enzyme that activates the mrna to correct the genetic error.
□ an enzyme that cuts dna.
□ trna that can replace the incorrect amino acid with the correct amino acid.
□ a virus that finds the genetic error.
□ a small piece of rna that directs the enzyme to the sequence of dna that needs to be fixed.

Explanation:

CRISPR technology uses a Cas enzyme (like Cas9) to cut DNA. A guide RNA (small piece of RNA) directs this enzyme to the specific DNA sequence for editing. mRNA activation (first option) isn't part of core CRISPR. tRNA (third option) is for translation, not CRISPR. Viruses (fourth option) aren't main components. So the two correct components are the DNA - cutting enzyme and the RNA that guides it.

Answer:

an enzyme that cuts DNA.
a small piece of RNA that directs the enzyme to the sequence of DNA that needs to be fixed.
