"To assemble the genome" means to put together the complete DNA sequence of an organism in the correct order. It involves analyzing and organizing smaller pieces of DNA to create a full picture of the genetic code of that organism. Full definition
Their primary mission is to produce a publicly available resource of high quality assembled genome sequences that researchers can use to address human biology and human health. (genome.gov)
Our group has been assembling genomes for many years, ranging from tiny (viruses and bacteria) to enormous (pine trees). (salzberg-lab.org)
A complete and fully assembled genome is critical for understanding the biological characteristics of an organism. (sciencedaily.com)
