Worked Solution & Example Answer:What type of structure must Cas9 be? A - HSC - SSCE Biology - Question 19 - 2019 - Paper 1
Step 1
What type of structure must Cas9 be?
Answer
Cas9 is a type of enzyme, specifically an endonuclease. It plays a crucial role in the CRISPR-Cas9 system, which is used for genome editing. Unlike other options presented, such as mRNA, ribosome, or tRNA, which have distinct functions in the process of gene expression and protein synthesis, Cas9 directly facilitates the cutting of DNA. Therefore, the correct answer is:
A. Enzyme.
