The discontinuous speed of transcription enables riboswitch molecules to adopt meta-stable structures in response to the presence of their cognate ligand, thereby gene-regulation by means of structure induced transcription termination can occur.
Internally tagged, functional Cse4/CENP-A/CenH3 histone variant is exclusively centromeric and stable through the budding yeast cell cycle after replacement in S phase.
Generation of stable transgenic opsin lines together with in vivo calibration of their efficacy using behavioural and electrophysiological assays constitutes a novel optogenetic toolkit in zebrafish.
A stable tetrameric nucleosome occupies the central segment of each ∼120-bp budding yeast centromere in two rotational phases of both reflectional orientations in vivo.
Running guinea fowl maintain stable running after loss of the stretch reflex in a major ankle extensor muscle, by increasing feedforward muscle activation to maintain ankle stiffness and work output.
Metabolomics and stable isotope labelling studies of virulent Mycobacterium tuberculosis reveal a de-centralised metabolic network able to utilise various amino acids as nitrogen sources to a better extent than ammonium.
Hippocampal neurons undergo bi-stable behavior as neurites emerge, and the dominance of either state is determined by environmental mechanical properties and paxillin-associated cellular endocytic activities.
