The hydrolyzing enzyme, myrosinase (a thioglucosidase), is stored in different cells than its substrates. While myrosinase-containing cells are mostly glucosinolate-free, the so-called sulfur-rich cells (or S-cells) contain high concentrations of glucosinolates.

Synaptic delay is due to the time it takes for the synaptic mediator to be released and to act on the receptors on the membrane of the postsynaptic cell. 

The minimum time for synaptic delay is 0.5 ms

Chromatin Immunoprecipitation (ChIP) is same as Chromosome Conformation Capture.

3C assays involve three basic steps:

(1) interacting chromosome segments are cross-linked with formaldehyde, 

(2) the DNA is digested, and

(3) cross-linked DNA fragments are ligated to produce products that are amplified and can be further analyzed.
