The phrase
"eukaryotic systems" refers to living organisms that have cells with a well-defined nucleus, such as plants and animals. Unlike simpler organisms like bacteria, eukaryotes have specialized compartments within their cells, which allows them to perform complex functions.
Full definition
However, the standard prokaryotic - based technologies lack the post translational modifications often necessary for desired function
in eukaryotic systems which led to the yeast - display methodology [7].
Bacterial signal transduction systems are capable of transmitting information from the exterior to a response using as few as two proteins
whereas eukaryotic systems typically use multiple components.
But now EPO apparently favors the UC argument that its discovery covers CRISPR use in both prokaryotic and
eukaryotic systems.
