UC San Diego genetic and synthetic biology research

Overview

Researchers at the University of California San Diego have made advancements in genomics and synthetic biology involving DNA and RNA processing.

Initial research utilized machine learning to decode the DNA sequence of the ‘initiator,’ a segment responsible for starting gene activation. By analyzing approximately 500,000 versions of the initiator, the team developed an AI model to identify the signature DNA patterns that dictate gene expression. This work allows for the prediction of how mutations might lead to disorders like cancer and could assist in designing synthetic promoters.

Subsequent research demonstrated that RNA polymerase can accurately read and process an expanded eight-letter genetic alphabet. Using high-resolution cryo-electron microscopy, scientists observed that the enzyme recognizes and incorporates synthetic base pairs using similar biochemical signals as natural ones. Furthermore, advancements in synthetic biology have produced AI-designed protein architectures that function as efficient, programmable RNA transport systems.
