Cells resolve unassigned codons with near-cognate suppression, frameshifting, and ribosomal rescue mechanisms, demonstrating that unassigned codons are permissible in both natural and engineered genetic codes as barriers to horizontal gene transfer.
The MYC transcription factor network member MGA is a subunit of a non-canonical Polycomb complex, which, when inactivated, accelerates tumorigenesis in mouse models of cancer and proliferation in colon organoids.
Racial and ethnic disparities in SARS-CoV-2 infection rates can impact overall epidemic dynamics and herd immunity, underscoring the need to develop socially informed transmission models that account for population variability.
Genome editing, advanced live-cell microscopy, and computational modeling were combined to measure WNT/CTNNB1 signaling parameters at the single molecule level, revealing critical regulatory nodes in this important signal transduction pathway.
The nature of the phycobilisome–photosystem II supercomplex on the native thylakoid determined with cryo-electron tomography at an unprecedented resolution reveals that one phycobilisome interconnects with six photosystem monomers.
