Sekvenssiosa

Sekvenssiosa is a Finnish term used in technical discussions to denote a contiguous portion of a sequence. The compound comprises sekvenssi (sequence) and osa (part or segment), and the expression is found in Finnish-language literature and documentation dealing with sequences in biology, information technology, and related fields. While not exclusive to a single discipline, sekvenssiosa generally refers to any extract of a longer sequence defined by start and end positions.

In genomics and biomolecular sequence analysis, a sekvenssiosa denotes a subsequence of a DNA, RNA, or protein sequence that is selected for study, comparison, or experimental design. In this sense the concept corresponds to the English term subsequence or fragment, though usage may vary by project or software. In data processing, time-series, and signal processing, sekvenssiosa may describe a contiguous block of samples or symbols extracted from a longer sequence for analysis, visualization, or processing in a sliding-window or batch approach.

The term is often used alongside related concepts such as full sequence (sekvenssi), segment (osa) and subsequence (alijono or osasegment, depending on context). Because Finnish technical vocabulary can differ between fields, it is advisable to consult field-specific glossaries or software documentation to determine the precise meaning in a given context.
