[Nfb-science] learning about DNA replication

[Aleeha Dudley]

Hi, 

     I am looking for a way to get a tactile representation of the processes
of DNA replication, transcription, and translation. The model needs to be
fairly specific as I am in an intro to biology course at the college level.
Does anyone know of such a thing or do you know of anything that helped you
when you were learning these concepts? 

Thanks, 

Aleeha
