RESUMO
La Biología sintética llegó para quedarse y expandir los límites de la ciencia. Numerosas técnicas moleculares que están siendo empleadas hoy en muchos laboratorios superaron la ficción para convertirse en una realidad. En este artículo se presentan dos técnicas innovadoras de la Biología sintética, como son la técnica de CRISPR, en especial la aplicación de CRISPR-on en la activación de genes específicos humanos, y el uso de ARN mensajeros sintéticos para la purificación y aislamiento celular. Con una mirada enfocada en la medicina traslacional, las herramientas de la Biología sintética ofrecen un gran potencial terapéutico. (AU)
Synthetic biology came to settle in and break the boundaries of the science. Many molecular techniques overcome the fiction to become reality. This article discusses two innovative techniques, as CRISPR, in particular the application of CRISPR-on which is able to activated particular human genes, and the synthetic RNAs messengers for isolation and purification specific cells. From a gaze focused on translational medicine, both tools offer great therapeutic potential. (AU)

DNA assembly is one of the most fundamental techniques in synthetic biology. Efficient methods can turn traditional DNA cloning into time-saving and higher efficiency practice, which is a foundation to accomplish the dreams of synthetic biologists for devising cellular architectures, reprogramming cellular behaviors, or creating synthetic cells. In this review, typical strategies of DNA assembly are discussed with special emphasis on the assembly of long and multiple DNA fragments into intact plasmids or assembled compositions. Constructively, all reported strategies were categorized into in vivo and in vitro types, and protocols are presented in a functional and practice-oriented way in order to portray the general nature of DNA assembly applications. Significantly, a five-step blueprint is proposed for devising cell architectures that produce valuable chemicals.
