Two protein structures from an avian influenza virus are shown below. One form of the protein makes influenza virus resistant to Oseltamivir (Tamiflu®) Don't worry, these proteins aren't from H5N1, but they do come from a related influenza virus that also infects birds.
National DNA Day has a fun challenge for teachers and classrooms using Pinterest.  Your class can join a larger, national, effort to create a National DNA Day Pinterest board by making your own class Pinterest board on DNA, genetics, and genomics.
I love using molecular structures as teaching tools. They're beautiful, they're easy to obtain, and working with them is fun.

DNA ?
Is this structure formed following reverse transcription of the viral RNA ?

This sequence was synthesized using phosphoramidite chemistry.
It corresponds to the cDNA sequence of the dimerization initiation site SL1 of HIV- 1(Lai) RNA.
