Verified step by step guidance

Understand that RNA sequences are composed of four bases: Adenine (A), Uracil (U), Cytosine (C), and Guanine (G). Unlike DNA, RNA contains Uracil (U) instead of Thymine (T).

Examine each given sequence and check for the presence of only the RNA bases (A, U, C, G). Any sequence containing Thymine (T) is a DNA sequence, not RNA.

Identify the sequence that contains Uracil (U) and does not contain Thymine (T), as this is a key indicator of an RNA strand.

Verify that the sequence is composed solely of valid RNA bases and that the order of bases is consistent with RNA structure.

Conclude that the sequence with only A, U, C, and G bases, and no T, correctly represents an RNA strand.
