Sejtmagotól

Sejtmagotól is a Hungarian adverbial phrase meaning “from the nucleus.” It is used in cell biology, genetics, and related fields to indicate the origin or source of a process, molecule, or signal that starts in the cell nucleus and acts in other cellular compartments.

The term is formed from sejtmag (nucleus) plus the suffix -tól, which marks direction or origin (from). In technical prose it is often used with nouns such as jel, információ, útvonal, or folyamat to specify that the source is the nucleus. The phrase is more common in formal scientific writing and may be complemented by possessive or participial forms (sejtmagtól érkező, sejtmagtól induló).

Usage and meaning: sejtmagtól describes origins in the nucleus and is typically used when contrasting nuclear-origin signals or mechanisms with those arising in other locations, such as the cytoplasm or extracellular space. It is often contrasted with sejtmagból (“from the nucleus and out into other compartments”) or with terms naming cytoplasmic origins.

Examples:

- A sejtmagtól érkező jel gyorsan eléri a citoplazmát.

- Sejtmagtól induló útvonalak fontosak a génexpresszió szabályozásában.

See also: sejtmag, citoplazma, transzkripció, jelátviteli útvonalak, sejtszabályozás.

Note: Sejtmagotól is a specialized, context-dependent phrase. In everyday Hungarian, more common alternatives include sejtmagból or sejtmagtól érkező/citoplazmából, depending on the exact nuance.
