sequencechromosome
Sequencechromosome is a term used in computational genomics to describe the digital sequence that represents a chromosome within a genome assembly. It denotes the contiguous nucleotide sequence that, together with other sequencechromosomes, forms the reference genome. The expression emphasizes the sequence-based nature of the chromosome rather than its physical, cellular form.
A sequencechromosome typically includes an identifier (such as chr1), the nucleotide sequence itself (A, C, G,
In practice, researchers use sequencechromosomes as the foundational reference for read alignment, variant calling, gene prediction,
Quality and limitations: sequencechromosome data may contain gaps or ambiguous bases (N), and some regions—such as
