Question

An IS (insertion sequence)element contains
A)a transposase gene only.
B)a transposase gene and additional genes.
C)a transposase gene and inverted repeats at the ends.
D)a transposase gene,additional genes,and inverted repeats at the ends.
E)genes but not a transposase gene.

Accepted Answer

An IS (insertion sequence) element is characterized by having a transposase gene, which is necessary for the element's movement within the genome, and inverted repeats at the ends, which are recognized by the transposase enzyme.
