Which one of the following DNA sequences carries an invert

Home » Genetics Ⅱ » Genetics-ⅱ Miscellaneous » Question

Which one of the following DNA sequences carries an invert repeat?

1. ATGAGCCCCGAGTA
  TACTCGGGGCTCAT
2. ATGAGCCGGCTCTA
  TACTCGGCCGAGAT
3. ATGAGCCGAGCCTA
  ACTCGGCTCGGAT
4. ATGAGCCTATGGTA:
  TACTCGGATACCAT

Correct Option: B

An inverted repeat (or IR) is a sequence of nucleotides followed downstream by its reverse complement. It is a sequence found in identical (but inverted) form, for example, at the opposite ends of a transposon.
Here, the DNA sequence which carries an inverted repeat is:
ATGAGCCCCGAGTA
TACTCGGGGCTCAT
