I believe it is the nucleus.
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.
Answer:
The correct answer is A. transplanted organs contain antigens that can trigger white blood cell activity
Explanation:
The body's immune system is designed to seek out and destroy any foreign object it finds in the body, such as a cold or flu virus - or a transplanted organ. The process of destruction of the transplanted organ is called rejection.Immunosuppressive drugs will be provided to prevent your immune system from damaging the transplanted organ. Organ transplants require the use of immunosuppressive drugs capable of controlling the immune response triggered by the presence of antigens foreign to the body itself. The group of immunosuppressants is made up of drugs indicated both in the prevention of rejection of the transplanted organ and in its reversal.
