Draft sequence
Draft Sequence
Draft Sequence (drahft see-kwens) is a term used in genomics and bioinformatics to refer to an initial, incomplete version of a genome sequence.
Etymology
The term "draft sequence" is derived from the English words "draft," meaning preliminary or initial, and "sequence," referring to the order of nucleotides in a DNA or RNA molecule.
Definition
A draft sequence is a preliminary version of a genome sequence that has not yet been finalized. It is typically produced in the early stages of genome sequencing projects, before the full sequence has been determined. The draft sequence may contain gaps, errors, or ambiguities, which are later resolved in the final, or "finished," sequence.
