Question

Which of the following DNA is made from RNA?

• A. A-DNA
• B. B-DNA
• C. C-DNA
• D. Z-DNA

Hint:

Reverse transcription is a process where RNA is used as a template to synthesize complementary DNA, typically leading to the formation of B-DNA.

Answer 1

The Correct Option is B

Step 1: Understand DNA forms. 
B-DNA is the most common form of DNA and can be synthesized from RNA in processes such as reverse transcription. 
Step 2: Analyze the options. 
A-DNA, C-DNA, and Z-DNA are different structural forms of DNA but are not directly made from RNA.
B-DNA is the form that is most commonly synthesized from RNA during reverse transcription in certain organisms. 
Conclusion: The correct answer is (B) B-DNA.
