End-synapsis Assay

BIO-PROTOCOL, 2013
Many environmental agents induce double-strand breaks (DSBs) in DNA. Unrepaired or improperly repaired DSBs can lead to cell death or cancer. Nonhomologous end joining is the primary DNA double-strand break repair pathway in eukaryotes. During NHEJ pathway, several proteins recognize and bind DNA ends, bring the ends in a synaptic complex and, finally,

Noise‐Limited Bit Precision in Ferroelectric Synaptic Transistors for High‐Resolution Neuromorphic Computing

Advanced Functional Materials, EarlyView.
Low‐frequency noise spectroscopy defines the resolvable conductance states of synaptic FeFETs by coupling read‐current fluctuation with usable dynamic range. The resulting noise‐limited bit precision establishes a universal, device‐agnostic reliability metric beyond the memory window, enabling quantitative benchmarking and rational design of high ...

Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

Advanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

Synapsis of loxP Sites by Cre Recombinase [PDF]

Journal of Biological Chemistry, 2007
Cre recombinase catalyzes site-specific recombination between 34-bp loxP sites in a variety of topological and cellular contexts. An obligatory step in the recombination reaction is the association, or synapsis, of Cre-bound loxP sites to form a tetrameric protein assembly that is competent for strand exchange.

Two distinct modes of meiotic chromosome synapsis

The pairwise alignment of homologous chromosomes within the synaptonemal complex (SC) is important for meiotic crossover recombination and fertility. However, chromosomes do not need sequence homology to synapse, with meiotic recombination defects often ...

Frequency (%) of PMCs with asynapsis, partial synapsis or complete synapsis of the 1RL arm in the six types of plants studied.

, 2012
Among PMCs of the 1R/1Rinv heterozygote with complete synapsis, 45% showed non-homologous synapsis and 55% homologous synapsis. Mean number of PMCs = 119±16.
