Codon Plot

Generate graphical plots of codon frequency for DNA sequences. Analyze codon usage and identify poorly expressed regions.

What is Codon Plot?

Codon Plot is a visualization tool that generates graphical representations of codon frequency in DNA sequences. It helps identify codon usage bias and potentially poorly expressed regions based on codon preferences.

How to Use This Codon Plot Tool

Generate codon frequency plots in three steps:

  1. Paste your DNA sequence (coding region)
  2. View the interactive bar chart visualization
  3. Analyze frequency data and download results

When to Use

This tool is useful when you need to:

  • Analyze codon usage patterns in genes
  • Identify rare codons that may affect expression
  • Compare codon usage between organisms
  • Optimize gene sequences for expression

Example Input

Sample DNA coding sequence:

ATGGCAGAAGAAGACTTCATTGCTTATATTGAGAACTTTGCAACTTCAGAAATTACAGAGGTGATGGAAGAGATGAAAAGCTTGTTGGAAAATCTCAACAGGCAGCTGAATTCAGAGGATCAGCTGAACATAAGCTAA

Try with your own sequence or use the Example button.

Example Output

Generated codon frequency analysis:

ATG: 3 (6.52%) GAA: 6 (13.04%) GCA: 2 (4.35%) ...

Plus interactive bar chart visualization.

FAQ

Q: What's the optimal sequence length?
A: At least 100 codons for meaningful statistics.

Q: How are frequencies calculated?
A: Count of each codon divided by total codons, shown as percentage.
