If the two RNA molecules are produced simultaneously, their sequences would be .......... to each other and this will result in formation of a double-stranded RNA

Options

A. Incompatible
B. Parallel
C. Complementary
D. Can't determine

Explanation

To solve the question, we need to analyze the relationship between the two RNA molecules produced simultaneously and understand what it means for their sequences to be related.

### Step-by-Step Solution:

1. **Understanding RNA Production**:
- When two RNA molecules are produced simultaneously, they are transcribed from complementary DNA strands. This means that each RNA strand is synthesized based on the sequence of the DNA template strand.

2. **Complementary Base Pairing**:
- RNA, like DNA, follows base pairing rules where adenine (A) pairs with uracil (U) and cytosine (C) pairs with guanine (G). Therefore, if one RNA molecule has a certain sequence, the other RNA molecule will have a sequence that complements it.

3. **Formation of Double-Stranded RNA**:
- When two RNA molecules are complementary to each other, they can hybridize or anneal to form a double-stranded RNA (dsRNA) structure. This is similar to how two strands of DNA come together to form a double helix.

4. **Conclusion**:
- Since the two RNA molecules are complementary to each other, this results in the formation of double-stranded RNA. Thus, the sequences of the two RNA molecules would be complementary.

### Final Answer:
The sequences of the two RNA molecules would be **complementary** to each other, resulting in the formation of double-stranded RNA.
