noun, plural: genomes
(1) The complete set of genetic material in anorganism
(2) The total genetic content in one set of chromosomes
According to Oxford Dictionary, the termgenomeis a portmanteau of the wordsgeneandchromosome.1However, Hans Winkler, a German botany professor, is the first to use the term in 1920.2In molecular biology and genetics, the term pertains to the complete set of genetic material in an organism. The genome ofeukaryotes包含在一个单身吗,haploidset of chromosomes. The genome of细菌包含在一个单身吗chromosomewhereas the genome ofvirusesis in theDNAorRNA.
The human genome is made up of approximately 35000 genes, or three billion chemicalbase pairs. The Human Genome Project, which was an international collaborative project from 1990 to 2003, was intended to identify the genes and the sequences of chemical base pairs in human DNA. However, the project sequenced only the euchromatic regions of the genome and not the heterochromaic regions in centromeres and telomeres.
