Integrons are
A) circular structures present in bacteria that contain genes encoding proteins and RNA and have the capacity to self-replicate and portion into daughter cells during cellular division.
B) DNA elements that encode transposition and excision function and can transpose from one place on the chromosome to another.
C) genetic elements capable of integrating resistance genes (cassettes) by an integron-encoded, site-specific recombinase.
D) DNA elements found in bacteria that carry genes only for the enzymes needed to promote their own transposition.

Question

Quizplus · Accepted Answer

Integrons are genetic elements that are capable of integrating resistance genes (cassettes) by an integron-encoded, site-specific recombinase. These cassettes are often present in mobile genetic elements such as plasmids or transposons and can be transferred between bacteria, contributing to the spread of antibiotic resistance.
