Construcción de modelos de Ingeniería Genética a través de la programación con Scratch

: is article presents a research focused on modeling and programming for the learning to Genetics Engineering (GI) in the high school. We designed, implemented and analyzed a didactic sequence around the construction of recombinant insulin in which the students had to build models by programming in Scratch. e models constructed were characterized from three theoretical categories linked to biological models: continuity, interaction and transformation and integration. Were obtained three types of models, in each type of model the categories analyzed were found in different levels of development. e students were able to conceptualize the GI and the modeling allowed them express the factors and processes necessary for the construction of rDNA molecule (recombinant DNA) using GI.
