Which represents a strand of RNA bases? a. TGGCTCGAA b. UGGCUCGAA c. GTTAGTGCC d. CAATCTAGG

Step 1: Define the Problem

Identify which option represents a strand of RNA bases.

Step 2: Break Down the Problem

Understand the difference between DNA and RNA bases:

• DNA bases: Adenine (A), Thymine (T), Cytosine (C), Guanine (G)
• RNA bases: Adenine (A), Uracil (U), Cytosine (C), Guanine (G)

Step 3: Apply Relevant Concepts

RNA strands contain Uracil (U) instead of Thymine (T).

Step 4: Analysis, Verify and Summarize

Analyze each option:

• a. TGGCTCGAA: Contains Thymine (T), not RNA
• b. UGGCUCGAA: Contains Uracil (U), possible RNA
• c. GTTAGTGCC: Contains Thymine (T), not RNA
• d. CAATCTAGG: Contains Thymine (T), not RNA

Final Answer

The strand that represents RNA bases is b. UGGCUCGAA.
