1. What is RNA to DNA Conversion?

RNA to DNA conversion (reverse transcription) is the process by which an RNA sequence is converted to its DNA complement. In this process, all uracil (U) bases are replaced with thymine (T) bases.

2. How Does the Calculator Work?

The calculator performs a simple base substitution:

Where:

• RNA — Input RNA sequence containing A, C, G, U bases
• DNA — Output DNA sequence with U replaced by T

Explanation: This simulates the biological process of reverse transcription where RNA is converted to complementary DNA (cDNA).

3. Importance of Reverse Transcription

Details: Reverse transcription is crucial in molecular biology for techniques like RT-PCR, cDNA library construction, and studying retroviruses like HIV.

4. Using the Calculator

Tips: Enter a valid RNA sequence (only A, C, G, U characters). The sequence is case-insensitive and will be converted to uppercase.

5. Frequently Asked Questions (FAQ)

Q1: Why replace U with T in DNA?
A: DNA uses thymine (T) instead of uracil (U) to pair with adenine (A). This is one of the key chemical differences between DNA and RNA.

Q2: Does this calculator handle the complementary strand?
A: No, this only replaces U with T. For full reverse complement, additional steps would be needed (reverse the sequence and complement each base).

Q3: What about modified bases?
A: This calculator only handles standard bases (A, C, G, U). Modified bases would need special handling.

Q4: Can I process very long sequences?
A: Yes, though extremely long sequences might impact performance in the web interface.

Q5: Is the input sequence validated?
A: Yes, the calculator checks that only valid RNA bases (A, C, G, U) are present in the input.
