Document Summary

Genome- organism"s entire complement of genetic information, including genes, regulatory sequences, and non-coding dna (cid:1) (cid:1) (cid:1) Genomics- discipline of mapping, sequencing, analyzing and comparing genomes (cid:1) Currently several thousand genomes of bacteria and archaea have been sequenced (cid:1) First genome sequenced was rna virus ms2 in 1976 consisting of. First bacterial genome was haemophilus influenza (in 1995) consisting of 1,830,137 bp (cid:1) Genomes of organisms are publically available in databases and include organisms with both circular and linear genomes (cid:1) Bacterial genomes range in size from about 0. 5 to 13 mbp and encode about 500 to 10,000 protein-coding genes, respectively (cid:1) The human genome contains about 3 billion bp but only about 25,000 protein-coding genes (cid:1) The largest genome currently sequenced is from the protozoan. Trichomonas, with about 60,000 protein-coding genes (cid:1) (cid:1) (cid:1) Sequencing- determining the precise order of nucleotides in a dna or.
