De novo genome assembly: what every biologist should know
As genome assembly programs stitch together an organism's chromosomes from fragmented reads of DNA, they perform some of the most complex computations in all of biology. Sanger sequencing, the...

Genome assembly in the telomere-to-telomere era - Nature
Genome sequences largely determine the biology and encode the history of an organism, and de novo assembly — the process of reconstructing the genome sequence of an organism from sequencing...

Ten steps to get started in Genome Assembly and Annotation
The most common approach to perform genome assemblies is de novo assembly, where the genome is reconstructed exclusively from the information of overlapping reads. For prokaryotes, it is also common to assemble with a reference genome, e.g., when complete strain collections are sequenced.

Genome Assembly - an overview | ScienceDirect Topics
A genome assembly is simply the sequence produced after all of the chromosomes of a target species have been fragmented (a large number of short/long DNA sequences), sequenced, and computationally put back together again to create a representation of the original intact chromosome sequences.

Sequence assembly - Wikipedia
Genome. The first sequence assemblers began to appear in the late 1980s and early 1990s as variants of simpler sequence alignment programs to piece together vast quantities of fragments generated by automated sequencing instruments called DNA sequencers. [2] .

Assembly: a resource for assembled genomes at NCBI - PMC
The NCBI Assembly Resource (www.ncbi.nlm.nih.gov/assembly/) allows users to search the Assembly database to find genome assemblies of interest, helps them choose between different assemblies for the same species, and provides access to download data for the selected assembly.

Lecture 6: Genome Assembly - MIT OpenCourseWare
Assembly. Whole-genome “shotgun” sequencing starts by copying and fragmenting the DNA. (“Shotgun” refers to the random fragmentation of the whole genome; like it was fired from a shotgun) Input: Copy: Fragment: Courtesy of Ben Langmead. Used with permission.
