Duplikaati

Duplikaati is a Finnish term that denotes the act or result of creating a copy that is intended to be identical or functionally equivalent to the original. The word derives from Latin duplicatus and is used across different fields to refer to the process of making a second version that mirrors the first.

In everyday and technical contexts, duplikaati can describe duplicating physical objects, documents, or digital data. In information technology, it covers copying files, creating backups, and maintaining redundant systems. Deduplication is a related technique that identifies and eliminates exact duplicates to save storage space.

In biology, duplikaati (often discussed as gene or genome duplication) refers to events where a segment of DNA or an entire genome is copied. Such duplications can give rise to paralogous genes and contribute to evolutionary novelty and complexity. Mechanisms include unequal crossing over during meiosis, replication-based errors, and whole-genome duplication, which is common in many plant lineages and some animal groups.

Duplikaati also appears in media production and publishing, where it denotes reproducing content such as tapes, discs, or printed materials. In linguistics, duplication can refer to reduplication, a process in which a word or morpheme is repeated to express emphasis or grammatical meaning in certain languages.
