A dinoflagellate belongs to a eukaryotic lineage notable for unusual nuclear chromosome organization. Many species have persistently condensed DNA with low bulk histone abundance, while retained histones and alternative nucleoproteins caution against a universal histone-free description.

A genus of microbial eukaryotes with reduced mitochondrion-related organelles called mitosomes.

A microbial eukaryote whose mitosomes contain a sulfate activation pathway.^[ref]

Camelina sativa is an oilseed plant used to investigate engineered accumulation of long-chain omega-3 fatty acids. Agronomic productivity and the percentage of a target in seed oil are distinct measurements.

A member of the ciliate lineage, characterized in typical examples by cilia and distinct germline and somatic nuclear systems. Sexual and nuclear-development details differ across species.

Complementary questions concerning mechanism, development, adaptive function and evolutionary history.

An ethologist studies animal behaviour, connecting its immediate causes, development, function and evolutionary history. Comparing observation with controlled intervention helps separate what an animal does from why the behavior occurs.

$\mathrm{P}{\mathrm{h}}_3\mathrm{C}-\mathrm{O}-\mathrm{C}{\mathrm{H}}_2\mathrm{C}{\mathrm{H}}_3$, an ether formed by trapping a triphenylmethyl carbocation with ethanol, followed by deprotonation.

An epoxide is a three-membered cyclic ether. The small ring constrains bond geometry and makes ring opening an important reaction pathway.

A nucleophile can open the ring by forming a new carbon bond while breaking one carbon-oxygen bond. Acid activation changes the electronic preference, so the attacked position and stereochemical result depend on the substrate and reaction conditions.

A silyl ether contains an O–Si bond, commonly protecting an alcohol or phenol. Cleavage at electrophilic silicon releases an oxygen-centered anion under suitable conditions.

An ether with oxygen directly attached to a vinylic carbon, $\mathrm{R}-\mathrm{O}-\mathrm{CH}=\mathrm{C}{\mathrm{H}}_2$ in the simplest terminal example. oxygen resonance donation strongly differentiates the two alkene carbon shifts.

An alcohol protecting group that is often stable to strong bases and organometallic reagents but can be removed under mild acid conditions.

An ether with oxygen directly attached to an alkene carbon. Electrophilic activation and hydrolysis can convert an appropriate enol ether back to a carbonyl compound.

The FLAG tag is an engineered epitope tag with the eight-residue sequence DYKDDDDK. Tag-specific antibodies permit detection or affinity capture of a fused protein. Its short length makes it convenient but does not guarantee neutrality: placement near a targeting sequence or functional interface can change behaviour. Comparing the tagged construct with an appropriate untagged or independently validated version tests whether it preserves the relevant function. ^[ref]
