Although not mandatory, I encourage you to check if your sequence is valid. Be aware that, although you can paste either a DNA or a RNA sequence, some of the analyses are type-selective.
To check whether your sequence is valid, click the button below.
This function will count each base and the total number of bases of your sequence.
It will also calculate the percentage of each base.
| Base | Count | Percentage |
| Adenine | ||
| Thymine | ||
| Cytosine | ||
| Guanine | ||
| Uracyl | ||
| Total |
To search whether a sub-sequence inside your sequence, insert the sub-sequence you want to look for below. At this moment, this function will only return the first occurrence of the sub-sequence.
Updated 21-11-2016: Now this function will return ALL the occurences of the sub-sequence.

With this tool you can automatically get the complementary sequence of your DNA chain. Be aware that this functionallity
will not work work with messenger RNA sequences, as mRNA is single-stranded. To get the complementary sequence, please, click the button below:
This functionality will allow you to obtain your sequence as a DNA or RNA chains. It will automatically detect what kind
of sequence you pasted and convert it to the other type. Try it clicking the button below.
This tool works with both DNA and RNA sequences. Please, be aware that it doesn't discriminate between ORFs, so whatever translatable codon
will be translated to amino-acids.
| Frame | Amino acid sequence |
| Frame 0 | |
| Frame 1 | |
| Frame 2 |
NEW: find all the possible Open Reading Frames (ORFs) of your sequence. It will return all possible ORFs in the three possible frames,
please select the minimum length of the resulting protein.
To consider a ORF as valid, the sequence should have:
- A start codon, by now only ATG or AUG
- A stop codon, namely TAA/UAA, TAG/UAG, or TGA/UGA
- A minimum length of amino acids between the start and stop codons, provided by the user. The bigger the amino acid sequence, the more probable it is to be a valid ORF
