D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: (a) 5'-GAUCCG-3' and  3'-CUAGGC-5'
## CONCEPT FRAMEWORK
	**Primary Concept**: RNA Structure and Base Pairing
	**Related Topics**: Nucleic Acids, Molecular Biology, DNA vs RNA
	**Prerequisites**: Understanding of nucleotide bases and complementary base pairing.
## SOLUTION PATHWAY
**Given Information**:
	We need to identify a double-stranded RNA molecule from the given options.
	RNA uses the bases Adenine (A), Uracil (U), Guanine (G), and Cytosine (C).
	In RNA, A pairs with U, and G pairs with C.
**Method & Steps**:
	1. Understand Base Pairing in RNA:
		Reasoning: RNA strands are antiparallel and complementary.
		Rule: A pairs with U, and G pairs with C.
	2. Analyze the options:
		Working: Compare the given strands in each option to see if they are antiparallel and exhibit correct base pairing.
		Key Point: Double-stranded RNA will have complementary base pairing between the two strands.
	3. Identify the correct pair:
		Result: Option (a) has two strands that are antiparallel (5'-3' and 3'-5') and show proper complementary base pairing (G-C, A-U, U-A, C-G, C-G, G-C).
		Verification: The strands in option (a) are complementary and antiparallel, fulfilling the requirements for double-stranded RNA.
## OPTION ANALYSIS
[A] ✓: 5'-GAUCCG-3' and 3'-CUAGGC-5' are antiparallel and show correct A-U and G-C base pairing. This represents a valid double-stranded RNA molecule.
[B] :x: 5'-GAUCCG-3' and 5'-CUAGGC-3' are both in the 5'-3' direction. Double-stranded RNA must have antiparallel strands.
[C] :x: 5'-GAUCCG-3' and 3'-GAUCCG-5' are antiparallel, but they don't show correct base pairing for RNA (G should pair with C, and A with U). This would represent a double-stranded DNA with a single mismatch.
[D] :x: 5'-GAUCCG-3' and 5'-GAUCCG-3' are both in the 5'-3' direction. Double-stranded RNA must have antiparallel strands.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing DNA and RNA base pairing: Remember Uracil (U) replaces Thymine (T) in RNA.
		2. Ignoring strand direction: Strands must be antiparallel.
	**Quick Tips**:
		1. Remember the mnemonic 'Apples in the Tree, Cars in the Garage' (A-U, C-G) for RNA base pairing.
		2. Visualize the antiparallel nature of double-stranded nucleic acids as arrows pointing in opposite directions.
