This is the first release of the low-coverage 2.05X assembly of the two-toed sloth (Choloepus hoffmanni). The genome sequencing and assembly is provided by the Broad Institute.
The N50 size is the length such that 50% of the assembled genome lies in blocks of the N50 size or longer. The contigs have an N50 length of 2461 bp and 8.6 kb for supercontigs. The total number of bases in supercontigs is 2.34 Gb and in contigs is 1.95 Gb.
The project coordination and genome sequencing and assembly is provided by the Human Genome Sequencing Center at Baylor College of Medicine
Owing to the fragmentary nature of this preliminary assembly, it was necessary to arrange some scaffolds into "gene-scaffold" super-structures, in order to present complete genes. There are 8139 such gene-scaffolds, with identifiers of the form "GeneScaffold_1".
Mammalian Genome Project
Choloepus hoffmanni is one of 24 mammals that will be sequenced as part of the Mammalian Genome Project, funded by the National Institutes of Health (NIH). A group of species were chosen to maximise the branch length of the evolutionary tree while representing the diversity of mammalian species. Low-coverage 2X assemblies will be produced for these mammals and used in alignments for cross-species comparison. The aim is to increase our understanding of functional elements, especially in the human genome.
General information about this species can be found in Wikipedia.
