A typical transposon is flanked by:
A)resistance factors
B)inverted repeat terminals
C)RTF genes
D)repressor sites

Question

Quizplus · Accepted Answer

A typical transposon is flanked by inverted repeat terminals which are short, direct or inverted repeated sequences that act as recognition sites for transposase enzyme, and allow the transposon to be excised and reinserted into a new location. Resistance factors (A) are not necessarily present in all transposons, as they carry genes that confer resistance to antibiotics or toxins. RTF genes (C) are not a common feature of transposons. Repressor sites (D) can be present in some transposons, but they are not a universal feature.
