Short Identical Sequences at the Ends of an IS Sequence

Question

Short identical sequences at the ends of an IS sequence are known as
A) transposon telemorases.
B) inverted terminal repeats.
C) correlated terminal repeats.
D) transposable terminal repeats.
E) All of these f) None of these

Accepted Answer

These sequences are known as inverted terminal repeats (ITRs) and are characteristic of transposable elements such as insertion sequences (IS). They are used to identify and target specific transposable elements for excision or integration. The other options are not valid terms and are not related to IS sequences.
