What is the function of gel electrophoresis?

• to separate DNA fragments according to size and charge

• to cut DNA

• to recombine DNA

• to extract DNA

What is the function of a restriction enzyme?

• recognize specific palindromic DNA sequences

• facilitate gene insertion

• to restrict or prevent enzymes from cutting DNA

• To create sticky / blunt ends on the plasmid and gene of interest

What is the function of guide RNA in CRISPR-Cas9 system?

• Guide RNA helps in the replication of DNA.

• Guide RNA is responsible for repairing damaged DNA.

• Guide RNA guides the Cas9 enzyme to the target DNA sequence.

• Guide RNA acts as a template for protein synthesis.

Which enzyme is crucial for the process of PCR?

• DNA ligase

• RNA polymerase

• Taq polymerase

• Reverse transcriptase

What does complementary DNA (cDNA) represent?
