What is two?

100

A valuable method to precisely disconnect single neurites in intact animals without causing much collateral damage

What is laser ablation/microsurgery?

100

According to the figures, PLX-1 expression in C. elegans is predominantly in this tissue category.

What is non-neuronal tissue?

100

The overall effect of plexin knockouts on baseline neuromorphogenesis in intact animals.

What is no effect?

100

This is the rationale for choosing C. elegans for dissecting semaphorin/plexin function.

What is well-established model with a constrained number of plexins and semaphorins?

200

The only semaphorin that is secreted in C. elegans.

What is mab-20?

200

Knockout animals would express GFP here.

What is the nervous system?

300

 The plexin that binds to membrane-bound semaphorins.

What is PLX-1?

300

The specific class of neurons whose axons were targeted for microsurgery and behavioral analysis in this study.

What are motoneurons?

300

This null mutant increased swimming speed when compared to WT C. elegans.

What is mab-20?

300

The hypothesized signaling direction that could allow PLX-1 to directly affect motor neuron responses.

What is reverse signaling (from plexins to semaphorins)?

300

The journal this article was published in.

400

In addition to plexins, the other class of transmembrane proteins that can assist with Semaphorin binding.

What is a neuropilin co-receptor?

400

The method used to verify knockout animals expressed their specific strain upon their arrival, after crosses, and after the study.

What is polymerase chain reaction (PCR)?

400

The unit of speed used in this study.

What is μm/s?

400

The proposed explanation for faster swimming in mab-20 mutants.

What is a glycosylphosphatidylinositol (GPI) link?

500

This specific experimental control group underwent all handling steps—including cooling, immobilization, and mounting—but was not exposed to the laser.
