GC Content Calculator
GC Content Calculator: Calculate DNA/RNA GC Content
Calculate the GC content of a DNA or RNA sequence. Select the sequence type (DNA or RNA), input your sequence (using A, T, C, G for DNA; A, U, C, G for RNA) using the keypad or keyboard, then click Calculate to get the GC content percentage.
How It Works
Select the sequence type (DNA or RNA) using the dropdown, enter your sequence using the keypad or keyboard, then click “Calculate” to see the GC content. The calculator displays the total sequence length, GC count, and GC percentage.

About GC Content Calculator
The GC Content Calculator computes the percentage of guanine (G) and cytosine (C) nucleotides in a DNA or RNA sequence. It’s a useful tool for molecular biology research, as GC content can affect DNA stability and gene expression.
How to Use
- Select the sequence type (DNA or RNA) from the dropdown.
- Enter your sequence using the keypad buttons (A, T/U, C, G) or keyboard (case-insensitive).
- Click the “Calculate” button to compute the GC content. The page will scroll to the result.
- Click the “Clear” button to reset the sequence input and results.
- Click the “Share” button to copy the calculator’s URL to your clipboard for sharing.
- Click the “Embed” button to copy an iframe code for embedding the calculator on another website.
- The total sequence length, GC count, and GC percentage will be displayed, along with detailed step-by-step calculations below.

Important Notes
- The sequence must contain only valid nucleotides for the selected type: A, T, C, G for DNA; A, U, C, G for RNA (case-insensitive). Invalid characters or empty sequences will trigger an error.
- The “Share” and “Embed” buttons require a browser that supports the Clipboard API.
