Verified step by step guidance

Understand that RNA sequences are composed of the bases adenine (A), uracil (U), cytosine (C), and guanine (G). Unlike DNA, RNA contains uracil (U) instead of thymine (T).

Identify that the given sequence 'TGGAAC TCA' is a DNA sequence because it contains thymine (T).

To find the RNA sequence, first determine the complementary DNA strand by pairing bases: A pairs with T, T pairs with A, G pairs with C, and C pairs with G.

Once the complementary DNA strand is found, transcribe it into RNA by replacing all thymine (T) bases with uracil (U). This means every T in the complementary strand becomes U in the RNA sequence.

Compare the resulting RNA sequence with the provided options to identify which one matches the transcribed RNA strand.
