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: Alexandrium catenella is a species of dinoflagellates. Alexandrium has two flagella that enable it to swim. While one flagellum encircles the cell causing the cell to rotate and move forward, the other extends behind the cell and controls the direction.
The cell wall is composed of cellulose Theca.
Length 20 - 48 μm, width 18 - 34 μm
Yellow-green to orange-brown
Forms chains of 2, 4 or 8 cells
