Cas9 cleaves both strands of the target DNA. Which of the following could occur when cells will try to repair the damage after c
Aloiza [94]

The correct answers are: the insertion of a DNA sequence into the targeted gene and deletions of the targeted gene

Cas9 is an enzyme endonuclease (which means it cuts nucleotides) that is part of the CRISPR-Cas9 complex- genome editing tool that can remove, add or alter sections of the DNA sequence.

Cas9 recognize the sequence that is going to be cut thanks to guide RNA- pre-designed RNA sequence complementary to sequence of interest. DNA repair machinery will try to fix the “damage” but it can add (insert) or delete some nucleotides.

gavmur [86]

According to the research, the correct option is uni-axial synovial joint. When considering the classification of joints based on the shape of the articulating bone ends, the knee functions as a type of synovial joint are called a <u>uni-axial synovial joint</u>.

<h3>What are uni-axial synovial joints?</h3>

They are synovial joints because they have cartilage and a joint capsule that allow flexion and extension movement, and it is because they move in a single plane or axis that they are considered monoaxial.

In this sense, they can be located in the humeroulnar joint located in the elbow, in the femorotibial or knee joint, allowing the rear sides of the leg to be moved away or closer, and finally in the joints that form between the phalanges of the fingers.

Therefore, we can conclude that according to the research, the correct option is uni-axial synovial joint. When considering the classification of joints based on the shape of the articulating bone ends, the knee functions as a type of synovial joint are called a <u>uni-axial synovial joint</u>.
