WebAbstract: We compared the sequence of a 101-kb-long bacterial artificial chromosome (BAC) clone (B21H13) from Brassica oleracea with its homologous region in Arabidopsis thaliana. This clone contains a gene family involved in the synthesis of aliphatic glucosinolates. The A. thaliana homologs for this gene family are located on … WebShotgun sequencingis when a genomic library is constructed by ligating random genomic DNA fragments into a vector, and then randomly sequencing these clones. The sequence data are then assembled into contigs using computers that determine regions of overlap. forest teljes film magyarul
