A
5' AATCG CGATT

5' AATCG TTAGC
D
5' AATCG GCTAA
Verified step by step guidance1
Understand that an inverted repeat sequence is a sequence of nucleotides followed downstream by its reverse complement.
Identify the given sequences and their reverse complements. For example, the reverse complement of 5' AATCG is 5' CGATT.
Compare each option to see if the sequence is followed by its reverse complement. For instance, check if 5' AATCG is followed by 5' CGATT.
Analyze each option: 5' AATCG CGATT, 5' AATCG AATCG, 5' AATCG TTAGC, and 5' AATCG GCTAA, to determine which one has the reverse complement immediately following the sequence.
Conclude that the sequence 5' AATCG CGATT is an example of an inverted repeat because it is followed by its reverse complement, 5' CGATT.
