Basic nucleotide manipulations at the address bar!
The DNA Helper extension providers useful and common nucleotide sequence manipulations at the address bar! Simply type "DNAHelper" in the address bar, then paste your DNA or RNA sequence. Choose to either reverse, complement, or reverse-complement your sequence as DNA or RNA -- the resultant sequence is copied to your clipboard! Avoid the extra time of finding a website to modify your sequence and use DNA Helper!
If you find this extension useful, consider installing my other extension, BLAST for Chrome.
