WebJan 20, 2004 · A model for crossovers formation without resolution of double Holliday junctions. After single-end invasion, Mus81–Eme1 cleaves the D-loop, which should topologically stabilize single-end invasion. Second-end capture and DNA synthesis produces a nicked Holliday junction subject to a second, possibly independent, cleavage by … WebNov 11, 2024 · This halopyridylation transformation is enabled by domino photocatalytic oxidative quenching activation and radical-polar crossover pathway.

The axons of the first-order neurons are localized within the spinal ganglion. They enter the spinal cord from the posterior … See more There are two spinothalamic tracts: anterior and lateral. The anterior spinothalamic tract transports course touch and pressure sensation. It is located in the anterior funiculus of the spinal cord. The lateral … See more Now that we understand the tracts involved in somatosensation, how are they integrated with movement? For example, how can our fingers follow the rim of a glass, or how can we walk in a coordinated fashion? … See more The spino-olivary tract (a.k.a.
