"Pajitex": una propuesta de modelo didáctico para la enseñanza de ácidos nucleicos.

This paper presents a three-dimensional teaching model for nucleic acids (DNA and RNA) using low cost material, such as: soda straws, scissors, elastic-type and needle lastex, which are of simple manipulation and easily found in the market. This teaching model suggests a pedagogical use of basic concepts and some issues related to nucleic acids, such as the semiconservative replication of the DNA molecule, transcription, genetic recombination, transgenic and gene therapy.
