Topic: protein production

This lecture traces research on the mouse T locus and the Tbxt gene before examining a proposed mechanism of tail loss in apes. A repeated DNA insertion may alter splicing and protein production. The discussion asks how a small genetic change could affect development and generate a large, persistent evolutionary transformation.

Katalin Karikó and Drew Weissman explain the scientific development of messenger RNA as a therapeutic platform. Their lectures address why laboratory-produced RNA can trigger inflammatory responses and how modification of its nucleosides changes immune recognition and improves protein production. The programme connects those molecular findings with the practical challenges of making RNA stable and delivering it into cells, including lipid-nanoparticle formulations. It follows the development of modified mRNA from a difficult experimental material to a foundation for vaccines and other therapeu
