Molecular biology explores the tiny machinery inside living cells, revealing how genetic instructions are read, copied, and turned into the proteins that keep us alive. This field acts as a bridge between the static code of DNA and the dynamic processes that drive growth, disease, and life itself, offering insights into everything from cellular repair to the development of new medicines.
On Gist.Science, we track every new preprint uploaded to bioRxiv in this category to make these complex discoveries accessible to everyone.

Below are the latest molecular biology papers freshly processed from bioRxiv, ready for you to explore and understand.
The study introduces TrueLAMP, a colorimetric LAMP formulation that effectively suppresses primer-driven nonspecific amplification to achieve 100% specificity and stable endpoint detection across various heating devices, thereby enhancing the reliability of isothermal nucleic acid testing without compromising sensitivity.
This study reveals that peptidomimetic inhibitors promote SARS-CoV-2 main protease dimerization by rigidifying the interface, whereas ebselen disrupts dimerization via an allosteric covalent modification at C300, highlighting distinct inhibitory mechanisms for future drug design.
This study reveals that the microtubule plus-end tracking protein Bim1 interacts with the S. cerevisiae Ndc80 complex via a conserved SxIP motif and a secondary helical site to strengthen microtubule attachments, a process that is regulated by Ipl1/Aurora B kinase-mediated phosphorylation to facilitate the destabilization of erroneous kinetochore-microtubule connections during error correction.
This study presents cryo-EM structures of the metabolic receptor GPR119 bound to its endogenous lipid agonist OEA in complex with Gs and Gq proteins, revealing how distinct ligand conformations and an extended TM5 helix govern G protein selectivity to provide a structural basis for developing pathway-specific therapeutics.
This study utilizes single-nucleus RNA-sequencing to reveal that while mechanical overload induces a youthful transcriptional signature in aged resident myonuclei, the age of the host muscle dictates the divergent terminal transcriptional states of skeletal muscle stem cell-derived myonuclei, directing them toward neuromuscular junctions in aged muscle and myotendinous junctions in adult muscle through Runx1-mediated specialization.
This paper introduces nCasTLES, a nanopore-based targeted sequencing method using Cas12a-generated overhangs for bead enrichment that eliminates inert off-target DNA, thereby enabling high-coverage profiling of genomic elements and modifications while significantly improving flow cell throughput and allowing for the simultaneous analysis of whole-genome libraries.
This study reveals that the cell nucleus functions as an active, transcription-driven microgel network poised near a sol-gel transition, where RNA production and degradation dynamically tune its connectivity to reconcile solid-like and fluid-like behaviors and regulate molecular transport.
This study demonstrates that CpG islands function as sequence-encoded topological sinks that buffer transcription-induced DNA supercoiling by leveraging their intrinsic physical properties to promote nucleosome depletion and localized DNA melting, thereby maintaining promoter architecture and genome stability.
This study demonstrates that the position of premature termination codons critically dictates both the cell-to-cell variability of nonsense-mediated mRNA decay efficiency and the resulting spectrum of protein products, thereby contributing to proteomic diversity and the variable severity of genetic diseases.
This study demonstrates that the degree of irregularity in nucleosome positioning acts as a physical switch governing a transition from compact, ordered chromatin to a dynamic, liquid-like state, thereby tuning chromatin accessibility and mechanical fragility to regulate gene expression.
