WebChromosomes, scaffolds and contigs Genome assemblies are hierarchical. The shortest assembly components are contigs, which are sequences taken from individuals. Contigs are assembled into longer scaffolds, and scaffolds are assembled into chromosomes if there is sufficient mapping information. WebDec 31, 2024 · Background: One of the important steps in the process of assembling a genome sequence from short reads is scaffolding, in which the contigs in a draft genome are ordered and oriented into scaffolds.
