Question

Which of the following is a soluble RNA?

• A. m-RNA
• B. r-RNA
• C. c-RNA
• D. t-RNA

Hint:

m-RNA is the only soluble RNA type, essential for transferring genetic information during protein synthesis.

Answer 1

The Correct Option is A

Step 1: Understand RNA types.
There are several types of RNA involved in protein synthesis, each with distinct roles.
Step 2: Review the options.
- m-RNA (messenger RNA) is soluble and carries genetic information from DNA to the ribosome for protein synthesis.
- r-RNA (ribosomal RNA) is part of the ribosome structure but is not considered soluble.
- c-RNA is not a recognized standard RNA type.
- t-RNA (transfer RNA) is involved in protein synthesis but is not classified as soluble RNA.
Step 3: Conclude.
m-RNA is the soluble form of RNA, making option (A) the correct answer.
Final Answer: \[ \boxed{\text{m-RNA}} \]
