3. 

What is the term used for a segment of DNA with one or more genes in the centre and the two ends carrying inverted repeat sequences of nucleotides?

The answer should be C: IS = Insertion sequence because transposon are two types:

IS which are genes flanked at both ends by inverted repeats.

And Composite which are genes flanked at both ends by IS.

I think the answer will be C: insertion sequence.

For example attenuator in trp operon where a sequence of U and U represents inverted repeat seq, and the inner carries strongly paired nucleotides.
