Question

The question is: Find the human (Homo sapiens) entry on the Entrez Genome page.Why are there three links to each chromosome? Make sure to provideevidence for your explanation. The link is: http://www.ncbi.nlm.nih.gov/genomes/genlist.cgi?taxid=2759&type=0&name=Complete%20Eukaryota At this Website, if you "control find" homo sapien, you willsee that there are three links to each chromosome (1, 2, 3 ...x,y). Does anyone know why? Thank you!! The question is: Find the human (Homo sapiens) entry on the Entrez Genome page.Why are there three links to each chromosome?

Explanation / Answer

The different links refer to different sequencing methods/projectused to produce the genome. For example if you go to the NCBIpage and searchgenomes for "homo sapiens chromosome 21"you will see the threereferences numbers also appear for chromosome 21 on the page youprovided.   NC_000021 corresponds to Homo sapiens chromosome 21, GRCh37primary reference assembly AC_000153 corresponds to Homo sapiens chromosome 21, alternateassembly (based on HuRef), whole genome shotgun sequence AC_000064 corresponds to Homo sapiens chromosome 21, alternateassembly (based on Celera), whole genome shotgun sequence
