This is a relatively simply stack for those in molecular biology and related fields who want to keep track of oligonucleotides. If you don't know what I'm talking about, you don't need this stack!
You need to type in the sequence of the oligonucleotide and its absorbance at 260nm. The stack will then calculate the base composition, length, and concentration (based on the nucleotide sequence and length). There is also a hot text list allowing you to jump to a particular card by clicking on a list entry. There's not much more to say about this stack, so have fun.
If you have any questions or ideas on improvements (or want to flame me for some mistake) please do so!
