1. What is DNA Sequence Length?

The DNA sequence length (L) is the number of nucleotide bases in a DNA sequence. It's a fundamental measurement in molecular biology and genetics research.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( L \) — Length in bases
• \( DNA \) — DNA sequence string (A, T, C, G)

Explanation: The calculator counts each character in the input string to determine the total sequence length.

3. Importance of Sequence Length

Details: Sequence length is crucial for PCR primer design, gel electrophoresis, sequencing analysis, and many molecular biology applications.

4. Using the Calculator

Tips: Paste your DNA sequence (A, T, C, G characters only) into the text box. The calculator will count all characters, including any spaces or line breaks.

5. Frequently Asked Questions (FAQ)

Q1: Does case sensitivity matter?
A: No, the calculator counts both uppercase and lowercase letters (A = a, T = t, etc.).

Q2: What about ambiguous bases?
A: All characters are counted, including ambiguous bases (N, R, Y, etc.) and non-standard characters.

Q3: Does it count spaces and line breaks?
A: Yes, all characters in the input are counted. For accurate results, remove any non-sequence characters first.

Q4: What's the maximum sequence length it can handle?
A: The calculator can handle sequences up to several million bases long (limited only by browser memory).

Q5: Can I use this for RNA sequences?
A: Yes, though you should convert U to T first if you want DNA-equivalent length.
