  • 355: Bacteria Complete Your tRNA
    May 9 2026

    TWiM explains how an enhanced domestication method allows for growth of uncultured bacteria, and identification of the oncogene SLC35F2 as is a high-specificity transporter for the micronutrients queuine and queuosine.

    Hosts: Vincent Racaniello, Michael Schmidt, and Michele Swanson.

    Guest: Mark O. Martin
